For paths to be consider equal, they must have the same routes attributes, such as weight, local preference, origin and AS_Path attributes are the same. If any of these attribues are different, BGP multipath will NOT take effect.
But in a special case, we can use the set protocols bgp[vrf<vrf-name>]bestpath as-path multipath-relax [as-set|no-as-set] command to configure Border Gateway Protocol (BGP) to treat two BGP routes as equal cost even if their AS-paths differ, as long as their AS-path lengths and other relevant attributes are the same. This allows routes with different AS-paths to be programmed into the forwarding table as equal cost multipath routes. Any changes in BGP configuration are applied by restarting the current BGP sessions on the VRFs.
