18 • RIP configuration
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
Example:
Enabling the poison reverse algorithm
The following example shows how to enable the poison reverse algorithm on IP interface wan on an IPLink.
IPLink(cfg)#context ip router
IPLink(ctx-ip)[router]#interface wan
IPLink(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
Example:
Enabling holding down aged routes
The following example shows how to enable holding down of aged routes on IP interface wan on an IPLink.
IPLink(cfg)#context ip router
IPLink(ctx-ip)[router]#interface wan
IPLink(if-ip)[wan]#rip route-holddown
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
