Comparing identical routes received from different external peers

Syntax:

[no] bgp bestpath compare-router-id

To configure a Border Gateway Protocol (BGP) routing process to compare identical routes received from different external peers during the best path selection process and to select the route with the lowest router ID as the best path, use the bgp bestpath compare-routerid command in router configuration mode. To return the BGP routing process to the default operation, use the no form of this command.

The behavior of this command is disabled by default; BGP selects the route that was received first when two routes with identical attributes are received.
