By default, no load balancing is configured.
Unlike IGP, BGP has no explicit metric for making load balancing decision. Instead,
it implements load balancing using route selection rules.
Related commands: display bgp routing-table.
Examples # In BGP view, set the number of routes participating in BGP load balancing to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] balance 2
# In BGP-VPN instance view, set the number of routes participating in BGP load
balancing to 2 (the VPN has been created).
<Sysname> system-view
