Enabling prefix suppression
Perform this task to disable an interface from advertising its prefix in LSPs. This enhances network
security by preventing IP routing to the interval nodes and speeds up network convergence.
To enable prefix suppression:
Command
isis ipv6 tag tag
Command
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
cost-style { wide | wide-compatible |
compatible }
address-family ipv6 [ unicast ]
multi-topology [ compatible ]
timer spf maximum-interval
[ minimum-interval
[ incremental-interval ] ]
Command
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
cost-style { wide | wide-compatible |
compatible }
address-family ipv6 [ unicast ]
multi-topology [ compatible ]
