Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide If enabled, the BGP process will compare the confederation AS path length of the routes received. The shorter the confederation AS path length, the better the route is. You can verify your settings by entering show ip bgp parameters command. Example This example shows how to enable the BGP process to compare the AS path that contains some confederation AS numbers. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 65534 DXS-3600-32S(config-router)#bgp bestpath compare-confed-aspath DXS-3600-32S(config-router)# 7-9 bgp bestpath compare-routerid This command is used to compare the router ID for identical eBGP paths. Use the no command to revert to disable this function. bgp bestpath compare-routerid no bgp bestpath compare-routerid Parameters Default Command Mode Command Default Level Usage Guideline None. BGP receives routes with identical eBGP paths from eBGP peers and selects the first route received as the best path. Router Configuration. Level: 8. (EI Mode Only Command) When comparing similar routes from peers the BGP router does not consider router ID of the routes. By default, it selects the first received route. Use this command to include router ID in the selection process; similar routes are compared and the route with lowest router ID is selected. 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. You can verify your settings by entering show ip bgp parameters command. Example This example shows how to configure to compare the router ID for identical eBGP paths for the autonomous system 65534. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 65534 DXS-3600-32S(config-router)#bgp bestpath compare-routerid DXS-3600-32S(config-router)# 7-10 bgp bestpath med confed This command is used to configure a BGP routing process to compare the Multi Exit Discriminator (MED) between paths learned form confederation peers. To disable MED comparison of paths received from confederation peers, use the no form of this command. bgp bestpath med confed no bgp bestpath med confed Parameters Default Command Mode None. By default, this option is disabled. Router Configuration. 70
