Hello, I would like to know when does Multipath kick in the BGP path selection process.
lets say, i have 2 routers, rtrA and rtrB connected with two physical links. First, For example, if i were to configure rtrA with 'multipath' and if rtrB would advertise a prefix on one session with shorter as_path. would rtrA load balance or would that break it? Second, I heard the following, is this true, if i have EIbgp multipath configured. (mpls vpn environment) if rtrA is Cisco and receives route 192.168/24 with AS_PATH 100 200 and AS_PATH 100 300. Cisco routers would not consider them to be the same even though the length is the same but the ASN's are different and move on to the next process in BGP decision process and break eibgp multipath. However, if rtrA were a juniper, the AS_path length would be considered the same and rtrA would load balance. If so, are there any knobs to change this? Last, whats the equivalent of maximum-paths eibgp in juniper? Any pointers or documentation that explains more on this would be appreciated. (rfc's, whitepapers, search terms to use, books, etc) Sincerely, -- Tim _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
