6. (Optional) Run:
load-balancing as-path-ignore
The router is configured not to compare the AS_Path attributes of the routes to be used
for load balancing.
By default, the router compares the AS_Path attributes of the routes to be used for
load balancing.
NOTE
l After the load-balancing as-path-ignore command is run, the router 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.
Set the maximum number of labeled BGP routes for load balancing.
Load balancing among labeled BGP routes is applicable to BGP LSP scenarios, such as
inter-AS VPN Option C and seamless MPLS scenarios. After load balancing is configured
among labeled BGP routes on the ingress of a BGP LSP, they can load-balance traffic as
long as equal-cost labeled BGP routes exist, which improves network bandwidth utilization.
1. Run:
system-view
The system view is displayed.
2. Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
3. (Optional) Run:
ipv4-family unicast
The BGP-IPv4 unicast address family view is displayed.
4. Run:
maximum load-balancing ingress-lsp number
The maximum number of labeled BGP routes is set for load balancing.
By default, the maximum number of labeled BGP routes for load balancing is 1.
5. (Optional) Run:
bestroute igp-metric-ignore
BGP labeled routes can be selected, regardless of their IGP metric values.
By default, BGP labeled routes with the same destination but different next-hop metric
values cannot balance traffic. To enable these routes to balance traffic, run the
bestroute igp-metric-ignore command. After this command is run, routes can be
selected to balance traffic, regardless of their IGP metric values. Exercise caution
when using this command.
