Usage guidelines
Unlike IGP, BGP has no explicit metric for making load balancing decision. Instead, it implements load
balancing by using route selection rules.
If you do not provide the ibgp or the ebgp keyword, this command configures load balancing for all BGP
routes.
After you execute the balance ibgp number or the balance ebgp number command, the balance number
command cannot be executed. To execute the balance number command, you must first use the undo
form of the balance ibgp number or balance ebgp number command to remove the former configuration.
Examples
# In BGP view, set the number of BGP ECMP routes to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] balance 2
# In BGP view, set the number of IBGP ECMP routes to 2.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] balance ibgp 2
# In BGP view, set the number of EBGP ECMP routes to 2.
