DGS-6604 bgp bestpath compare-routerid bgp bestpath compare-routerid Use this command to compare router IDs for the best-path selection process when external BGP (eBGP) paths are identical. Use the no form of the command to disable this function. bgp bestpath compare-routerid no bgp bestpath compare-routerid Syntax None Default Command Mode BGP receives routes with identical eBGP paths from eBGP peers and selects the first route received as the best path. Router configuration Usage Guideline Example When comparing similar routes from peers the BGP router does not consider the router ID of the routes. By default, it selects the first received route. Use this command to include the router ID in the selection process. When enabled, similar routes are compared and the route with the lowest router ID is selected. Unless manually defined, the router ID is the highest IP address on the router, with preference given to loopback addresses. Router ID can be manually set by using the bgp router-id command on page 78. This example shows how to configure to compare the router-ids of identical eBGP paths for autonomous system 65534: Switch(config)# router bgp 65534 Switch(config-router)# bgp bestpath compare-routerid CLI Reference Guide 72
