We are using two cisco 7200, IOS 12.4, both connected to a different ISP with BGP and iBGP between them.
Both providers send us some routes with well-know communities that prevent some route being advertize in iBGP between routers.
I would like to create a route-map to remove all those well-know attribute to make sure both router have full a set of routes from both ISP.
We already use filters to prevent advertizing routes learn from one ISP to the other.
Is there a standard way to clear all community attributes, using route-map or any other way ?
