To do… Use the command… Remarks
Enter system view system-view —
Create a RIP process and enter
RIP view
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
Required
By default, RIP is disabled.

connected, namely, one hop away from each other.
z Using the undo peer command does not remove the neighbor relationship at once and therefore
cannot bring down the BFD session at once.
