Hidden Commands

BGP

With BGP you have the option to do ECMP. By default BGP will only allow doing ECMP on external prefixes if they come from the same AS. You canĀ relax this multi-pathing using this BGP global command:

! BGP AS-path Multi-path Relax:
R1(config)#router bgp 1
R1(config-router)#bgp bestpath as-path multipath-relax
R1(config-router)#address-family ipv4
R1(config-router-af)#maximum-paths 2
