Chapter 18 | Unicast Routing
Configuring the Routing Information Protocol
– 671 –
◆ Instability Prevention – Specifies the method used to reduce the convergence
time when the network topology changes, and to prevent RIP protocol
messages from looping back to the source router.
■
Split Horizon – This method never propagate routes back to an interface
from which they have been acquired.
■
Poison Reverse – This method propagates routes back to an interface from
which they have been acquired, but sets the distance-vector metrics to
infinity. This provides faster convergence. (This is the default setting.)
■
None – No loopback prevention method is employed. If a loop occurs
without using any prevention method, the hop count for a route may be
gradually incremented to infinity (that is, 16) before the route is deemed
unreachable.
Web Interface
To network interface settings for RIP:
1. Click Routing Protocol, RIP, Interface.
2. Select Add from the Action list.
3. Select a Layer 3 VLAN interface to participate in RIP. Select the RIP protocol
message types that will be received and sent. Select the RIP authentication
method and password. And then set the loopback prevention method.
4. Click Apply.
