Description

When integrating CNA into some highly customized network topologies, it may be advantageous to force a route assertion on a router even though BGP has already selected the route for a given prefix. (This will have at least one major consequence: CNA will not be able to recognize subsequent changes in the natural BGP selection.)

If you are sure this behavior is correct for your network, use the assert-routes-matching-bgp command to enable assert-matching-routes mode.

Use the no form of the command to disable assert-matching-routes mode.

When this mode is disabled (the default condition), CNA will not assert a performance route to a router when the CNA choice and the BGP selected route for the prefix are the same.

NOTE: If route assertion is not enabled (see the route-assert-mode command), the assert-routes-matching-bgp command will not have any affect on CNA operation.
