acquired over that interface. Poison reverse updates are then sent to remove the route and place it in hold-
down. One drawback is that routing update packet sizes will be increased when using poison reverse.
This procedure describes how to enable the poison reverse algorithm on an interface
Mode: Interface
Step Command
1 node (if-ip)[ name ]#rip poison-reverse Enables the poison reverse algorithm on interface name
Example: Enabling the poison reverse algorithm
The following example shows how to enable the poison reverse algorithm on IP interface wan on a Smart-
Node.
SN(cfg)#context ip router
SN(ctx-ip)[router]#interface wan
SN(if-ip)[wan]#rip poison-reverse

Enabling holding down aged routes

Holding down or locking aged routes learned from RIP packets on the specified interface helps, if an aged
route cannot be refreshed to a non-aged status but must be deleted and then relearned. Enabling this function
enhances the stability of the RIP topology in the presence of transients.
This procedure describes how to enable holding down of aged routes on an interface
Mode: Interface
Step Command
node (if-ip)[ name ]#rip route-holddown Enables holding down aged routes on interface name

Displaying RIP configuration of an IP interface
Displaying the RIP configuration of an IP interface is useful to list the settings. This procedure describes how
to display the RIP configuration of an interface
