Usage guidelines

For BGP to implement load balancing over routes with different AS_PATH attributes, you must use this command together with the balance command.

After this command is executed, BGP ignores the AS_PATH attributes in the routes for load balancing and changes the attributes of the advertised routes to those of the optimal route. The operations might cause routing loops. Therefore, use this command with caution.

Examples

# In BGP IPv4 unicast address family view, enable BGP to ignore the AS_PATH attribute when it implements load balancing.

<Sysname> system-view
[Sysname] bgp 100
