Configuring RIP 10-21
Setting the Poison
Reverse Mode
The poison reverse mode allows you to prevent a routing loop if a route is
advertised on the interface on which it came in. Poison reverse has two
modes:
■ enabled — On the interface on which a route came in, RIP advertises
that the route is unavailable. Because the originating router does not
overwrite its routing table entry, a routing loop does not occur.
■ disabled — RIP does not advertise that a route is unavailable.
To set the poison reverse mode, from the top level of the Administration
Console, enter:
ip rip poisonReverse
Example:
Select interfaces (1-2|all):2
Enter RIP poison reverse mode (disabled,enabled) [enabled]:
Default
The default poison reverse mode is enabled.
Adding an RIP
Advertisement
Address
The system uses this IP address when it advertises routes to other stations
on the same subnetwork. In particular, the system uses this address for
sending RIP updates.
Default By default, the system uses a directed advertisement (all 1s in the host
field).
To add an RIP advertisement address to an IP interface:
1 From the top level of the Administration Console, enter:
ip rip addAdvertisement
2 Enter the RIP advertisement addresses that you want to add.
