NAME

roe (Route Object Editor)  

SYNOPSIS

roe [flags] [<as-no>]  

DESCRIPTION

roe is a C++/Tcl/Tk program that lists the routes registered by <as-no>. roe can be used to find discrepancies between the registered routes and the routes that are actually being routed. roe can be used to find all the holes that are punched in the AS's routes, or all the holes the AS punches in other routes. roe can be used to easily add, delete and update route objects in any IRR registry (hence the name editor). For example, one can register all the routes which are routed but not registered in couple of mouse clicks. If <as-no> is not specified it is deduced for your system from the IP address of your host and IRR.  

IRRToolSet COMMON OPTIONS

-help
Print summary of command-line options and abort.
-T [whois_query | whois_response | input | all]
Trace the argument. Useful for debugging.
-D <integer>
Print debugging messages of debug channel <integer> (if compiled with DEBUG defined).
-version
Print the version number and quit.
-h <host-name>
Establish a whois connection to host <host-name>. The default is whois.radb.net. This means that roe obtains its data only from <host-name>. If it displays routes from other registries, those are the mirror copies of those routes in <host-name>. However, roe can update any registry, not just <host-name>.
-p <port-no>
Establish a whois connection to port <port-no>. The default is 43.
-protocol <protocol>
Use the <protocol> to connect to the IRR server. <protocol> can be irrd(rawhoisd), ripe(bird), and ripe_perl. The default is irrd. The ripe_perl option should be used with the old ripe server.
-s <source-list>
Consider the sources specified in the comma separated <source-list>. For example, -s RADB,MCI,CANET,ANS,RIPE
-rusage
Print resource usage upon completion.
-ignore_errors
Do not print error and warning messages due to communication to the database server or parsing policy objects.
-report_errors
Print error and warning messages due to communication to the database server or parsing policy objects.
 

OTHER OPTIONS

-as <as-no>
Lists routes of <as-no>.
-rcfile <resource filename>
-display <X Windows Display Specification>
-geometry <X Windows Geometry Specification>
 

ENVIRONMENT VARIABLES

IRR_HOST
Specifies the IRR host to connect.
IRR_PORT
Specifies the IRR port number to connect.
IRR_SOURCES
Specifies the source list (comma separated) to consider.

Command line options take precedence over environment variables.  

USAGE

Invoke roe using your AS number,

        % roe AS226
roe will acquire and display the set of address prefixes that are registered with your AS as the origin. Afterwards, in the background, next to each address prefix it will display a set of IRR registry and AS number pairs. This information signifies that a route object for this prefix is registered in the IRR registry by the origin displayed. In addition, next to each route some of the followed words may be displayed:
NotReg
to signify that the route is not registered,
NotRtd
to signify that the route is not routed (according to a BGP dump),
OtrHmd
to signify that the route is homed to an AS other than yours,
MltHmd
to signify that the route is homed to more than one AS and one of which is your AS,
MHmOtr
to signify that the route is homed to more than one AS and none of which is your AS,
---
to signify that the route's status is not yet determined.

If you select an address prefix by clicking left mouse button on it, a set of buttons will be displayed, each corresponding to the registry and AS number pairs of the selected address prefix. Clicking on these buttons will display the object's definition in the lower left window. To delete (update or add) an object, press the delete (update or add) button, followed by the schedule button. In the lower right window, all the scheduled transactions are listed. You can select any of them to display the object which is scheduled. The selected transaction can be unscheduled by clicking on the cancel button. Transactions are carried out to update the IRR when the Update IRR button is pressed.

If you click on the Update IRR button, a set of windows will pop-up, one for each registry and maintainer pair. In this window make sure that the program to pipe is correct, and in the body of the message add any authorization words that may be necessary (such as passwords). Then, click either on the Update button or on the Cancel button to commit your scheduled transactions, or to skip them forever. The affect of your updates are not immediately shown on the display, since IRR currently may take up to a day to propagate all the changes back to the server that roe connected to.

It is possible to select more than one address prefixes. Selecting more than one address prefixes is useful for the commands in the menu bar. To select more than one address prefix which are not contiguous, click the left mouse button while holding the control key down. This toggles the selection status of the address prefix under the pointer. For more options, please refer to the default bindings section for the extended listboxes in Tk listbox man page.  

MENUS

File/Compare with BGP dump
A file name will be prompted. This file should contain the set of address prefixes that your AS originates. The file format is the following. Each line contains a classless address prefix (e.g. 128.8.0.0/15) or a classfull address (e.g. 128.9.0.0) followed by any other data which is skipped. A line that does not have either a classless or classfull address that starts in the first five columns is skipped. The BGP dump generated by the command "show ip BGP regexp ^$" meets the requirements of this file. If you have a BGP dump in another format, you should convert it to a file which lists the address prefixes (classless or classfull), one at a line.
File/Quit
This item causes roe to exit.

Show
roe displays address prefixes that match a display criteria. By default all address prefixes match the display criteria. Show menu changes the current display criteria. It consist of 4 parts. All parts are explained below in detail. The last three parts control the three main criteria, registration criterion, routed criterion, homed criterion. Each criterion can have several values. For a route to be shown on display it has to match one of the selected values of all three criteria. A common mistake is to select a value for one of the criterion and select no value for the other two criteria. This will not display any routes since no routes will match the other two criteria. Often what is meant can be achieved by selecting one value in one criterion and all values in the other criteria.

Show/Show None
This menu item makes no address prefix match the display criteria.
Show/Show All
This menu item makes all address prefixes match the display criteria.
Show/Show Again
Whether an address prefix matches the display criteria can change in time since certain criteria can only be determined after roe acquired the registration information from IRR, which it does in the background. This menu item redisplays the list of address prefixes using the information currently acquired.
Show/Not Registered
Match the set of address prefixes that are not registered in IRR. These address prefixes are most likely introduced by a compare with BGP dump operation.
Show/Singly Registered
Match the set of address prefixes that are registered by only one route object.
Show/Multi Registered
Match the set of address prefixes that are registered by more than one route object.
Show/Undetermined
Match the set of address prefixes for which neither of the above is determined yet.
Show/Routed
Match the set of address prefixes that are routed according to the BGP dumps compared.
Show/Not Routed
Match the set of address prefixes that are not routed according to the BGP dumps compared.
Show/Undetermined
Match the set of address prefixes for which neither of the above is determined yet.
Show/Single Homed to Your AS
Match the set of address prefixes that are registered by only your AS.
Show/Single Homed to Other AS
Match the set of address prefixes that are registered by only one AS other than your AS.
Show/Multi Homed
Match the set of address prefixes that are registered by more than one AS.
Show/Undetermined
Match the set of address prefixes for which neither of the above is determined yet.

Selection/Select All
Select all routes currently being displayed.
Selection/UnSelect All
Unselect all routes currently being displayed.
Selection/Add Selected Routes
Add a route object for all the selected address prefixes using the add template in the Configure/Templates menu.
Selection/Delete Selected Routes
Delete all route objects for the selected address prefixes from any registry that they are registered in, using the delete template in the Configure/Templates menu.
Selection/Delete Selected Routes from
Delete all route objects for the selected address prefixes from the registry that you will be prompted for, using the delete template in the Configure/Templates menu.
Selection/Get More Specifics
List any address prefix registered in IRR which is a more specific of the selected routes. This option takes around a minute or two when it is invoked for the first time.
Selection/Get Less Specifics
List any address prefix registered in IRR which is a less specific of the selected routes. This option takes around a minute or two when it is invoked for the first time.

If you are interested for the more specifics and less specifics of all your routes, do the following: (1) select all routes, (2) get more specifics, (3) select all routes, (4) get less specifics. If you change the order and get the less specifics first, you will display all the routes registered in IRR, since 0.0.0.0/0 is registered. Doing this requires significant amount of memory.

Configure/Templates
There are add, delete and update templates. The add template is used to create new route objects. It should contain all the attributes that you include in your route objects. You can (and should) refer to $ROUTE, $AS, and $DATE macros anywhere in your templates. These will be substituted by the actual address prefix, the as number and the current day correspondingly.

The update template is used when an object definition is updated. It should at least contain a changed attribute and may contain other attributes. The delete template is used when an object is going to be deleted. It should contain only the delete attribute, and no other attribute (if you put other attributes, the object will not be deleted since an exact match except for the delete attribute is required for deletion).

Configure/IRR Update Commands
A window displaying the IRR registries and the update commands will pop-up. Roe will pipe the data to the update command to update the corresponding registry.
Configure/Revert to Factory Settings
Change above configuration options to factory settings.
Configure/Save Options
Save the configuration options to file ~/.roerc.
Configure/Reload Options
Reload the configuration options from file ~/.roerc.

 

EXAMPLE USES

Following uses may be of interest. Prepare a BGP dump of your routes. Invoke roe. Do a "File/Compare with BGP dump". Wait till pending replies reaches 0.

1. Show "Not Registered" and "Routed" routes. Register all of these routes. You can use "Selection/Select All" followed by "Selection/Add Selected Routes".

2. Select "Not Routed", "Singly Registered", "Multi Registered" and "Single Homed to Your AS" routes. Unregister all of these routes. You can use "Selection/Select All" followed by "Selection/Delete Selected Routes".

3. Select "Not Routed", "Singly Registered", "Multi Registered" and "Multi Homed with Your AS" routes. Unregister only your own registrations. You need to do this one by one.

4. Select "Multi Registered", "Routed", and "Single Homed to Your AS" routes. You only need one copy of these routes in IRR. Pick one registry in IRR as your primary registry. Unregister the extra copies from the non-primary registries. You can use "Selection/Select All" followed by "Selection/Delete Selected Routes from".

 

FILES

roe creates a ~/.roerc file which stores the templates and the update commands. This file is not meant for hand editing.

 

SUGGESTION

Joachim Schmitz points out that it is not necessarily the best choice to use a "show ip bgp regex ^$" within the home AS (which is IBGP routes) to study consistency of route objects in the IRRs and the actual routes. He advises to get an EBGP table from an external peer using "show ip bgp regex ^<as-no>"

 

ERROR AND WARNING MESSAGES

AS number should start with "AS"

Syntax error in AS number, which should be AS<integer>.

Error: while parsing <yyline>

Yacc parser error on BGP dump file. This may be caused by wrong BGP dump format (see above).

Unknown protocol!

The connection to IRR failed. This can be caused by various reasons, see Errors manpage, IRR Communication errors.

No <asno> on IRR!

Originating aut-num is not found on IRR. You might mistype the source, hostname or as-number, or the object is truly non-existent.

No route for <as_no>

No route objects are originated from <as_no> (from IRR). This can be a typing mistake for the AS-number, or also truly error.

No object for <as_no>

No aut-num object is found on IRR for <as_no>

See above.

For more error descriptions, please see Error manual page.
