Parameters
number: Number of BGP routes participating in load balancing. The number ranges from 1 to 8. When
it is set to 1, load balancing is disabled.
Description
Use the balance command to configure the number of routes participating in IPv6 BGP load balancing.
Use the undo balance command to restore the default.
The feature is not available by default.
Unlike IGP, BGP has no explicit metric for making load balancing decision. Instead, it implements load
balancing by defining its routing rule.
Related commands: display bgp ipv6 routing-table.
Function
Used to create a summary route and suppress the advertisement of some
summarized routes. If you want to suppress some routes selectively and
leave other routes still advertised, use the if-match clause of the route-policy
command.
Selects only routes satisfying the routing policy for route summarization.
Sets attributes except the AS-PATH attribute for the summary route. The same
work can be done by using the peer route-policy command.
