16.1.6 Configuring Split-horizon Parameters
Normally, routers that are connected to broadcast-type IP networks and that use distance-vector
routing protocols employ the split horizon mechanism to reduce the possibility of routing loops.
Split horizon blocks information about routes from being advertised by a router out of any
interface from which that information originated. This behavior usually optimizes
communications among multiple routers, particularly when links are broken. However, with
non-broadcast networks (such as Frame Relay), situations can arise for which this behavior is
less than ideal. For these situations, you might want to disable split horizon for RIP.
You can avoid including routes in updates sent to the same gateway from which they were
learned. Using the split horizon command omits routes learned from one neighbor, in updates
sent to that neighbor. Using the poisoned parameter with this command includes such routes in
updates, but sets their metrics to infinity. Thus, advertising these routes means that they are not
reachable.
DUT# configure terminal Enter the Configure mode.
DUT(config)#interface eth-0-2 Specify interface eth-0-2 as the interface you want to configure.
DUT(config-if)# no ip rip split-horizon Disable split horizon for RIP.
DUT(config-if)# ip rip split-horizon Enable split horizon for RIP without poisoned reverse.
DUT(config-if)# ip rip split-horizon
poisoned Enable split horizon for RIP with poisoned reverse.
Validation Commands
show running-config, show ip rip interface
16.1.7 Configuring Timers
RIP use several timers that determine such variables as the frequency of routing updates, the
length of time before a route becomes invalid, and other parameters. You can adjust these timers
to tune RIP performance to better suit your internet-work needs. You can make the following
timer adjustments:
• The rate (time in seconds between updates) at which routing updates are sent
