To enable or disable split horizon, perform the following tasks in interface configuration mode.
Command Purpose
ip rip poison reverse Enable split horizon with poison reverse.
no ip rip poison reverse Disable split horizon with poison reverse.
5.4.11 Manage Authentication Keys
If you are sending and receiving RIP Version 2 packets, you can enable RIP authentication on an interface. RIP
Version 1 does not support authentication.
The IC35516 software supports two modes of authentication on an interface for which RIP authentication is enabled:
plain text authentication and MD5 authentication. The default authentication in every RIP Version 2 packet is plain
text authentication.
Important! Do not use plain text authentication in RIP packets for security purposes because the unencrypted
authentication key is sent in every RIP Version 2 packet. Use plain text authentication when security is not an issue
(for example, to ensure that incorrectly configured hosts do not participate in routing).
Command Purpose
ip rip authentication mode {text | md5} Configure the interface to use MD5 digest authentication or
let it default to simple password authentication.
ip rip authentication string string Set the interface with plain text authentication. The string
must be shorter than 16 characters.
5.4.12 Monitor and Maintain RIP
You can display specific router statistics, such as the contents of IP routing tables and databases, in order to monitor
and maintain RIP. Information provided can be used to determine resource utilization and solve network problems. It
is also possible to discover the routing path that the packets are taking through the network.
To display various router statistics, perform the following tasks in top mode.
Command Purpose
show ip rip Display general information about RIP routing processes in a
particular router.
show ip protocols Display the parameters and current state of the active routing
protocol process.
The debugging commands are helpful to quickly diagnose problems. Use the following commands in privileged top
configuration mode to display information on RIP routing transactions.
Command Purpose
debug ip rip events Display RIP events, including sending and receiving packets
and changes in interfaces.
