By default, the switch compares the AS-Path attributes of the routes to be used for
load balancing.
NOTE
l If there are multiple routes to the same destination but these routes pass through different
ASs, load balancing cannot be implemented among these routes by default. To implement
load balancing among these routes, run the load-balancing as-path-ignore command.
After the load-balancing as-path-ignore command is run, the device no longer compares
the AS-Path attributes of the routes to be used for load balancing. Therefore, exercise
caution when using this command.
l The load-balancing as-path-ignore and bestroute as-path-ignore commands are
mutually exclusive.
Run the display bgp ipv6 routing-table [ ipv6-address prefix-length ] command to check
routing information in an IPv6 BGP routing table.
Run the display ipv6 routing-table [ verbose ] command to view the IPv6 routing table.
