ListPath or GetRib to get routes based on community

[ramarkandasamy]

Our requirement is to get the routes based on community string. Is there any option in ListPath or GetRib or any other API provides that ?

I didn't find anything relating to this in the docs and in the API. The only option I see to emulate this feature with the current version is the following (overkill) workflow :

• create a policy using the API, matching the communities,...
• define a BGP peer and apply the policy to it
• start a local gobgp instance, and connect it to the target
• list path from local BGP instance using the ListPath API
• hope this does not mess up your network....

This feature is a must have and is present in many (maybe every ?) routers on the market. We are also interested in matching extended and large-communities, but it would be really nice to make it work with any policy. This would, for example, allow the following use-cases:

• testing a policy before applying it
• defining policies that look for specific routes (specific communities, internal, external, long routes, routes from specific AS...) and use ListPath requests to show them to the administrator.

The IOS-XR router works like this : you can create a route-policy that is used in a show command to "filter" the output, which makes it really flexible.
