Configuring RIP to redistribute routes from another protocol
n
The allow-ibgp keyword is used to redistribute iBGP routes. Because the AS-PATH
attribute of redistributed iBGP routes is discarded, routing loops may occur.
Therefore, use this keyword with caution.
RIP Network
Adjustment and
Optimization
In some special network environments, some RIP features need to be configured
and RIP network performance needs to be adjusted and optimized. By performing
the configuration mentioned in this section, the following can be implemented:
■
Changing the convergence speed of RIP network by adjusting RIP timers,
■
Avoiding routing loop by configuring split horizon,
■
Traffic sharing based on multiple equivalent routes,
■
Packet validation in network environments with high security requirements,
and
■
Configuring RIP feature on an interface or link with special requirements.
Configuration
Prerequisites
Before adjusting RIP, perform the following tasks:
■
Configuring the network layer addresses of interfaces so that adjacent nodes
are reachable to each other at the network layer
■
Configuring basic RIP functions
Enable RIP traffic sharing
across interfaces traffic-share-across-interface Optional
By default, RIP traffic
sharing across interfaces
is disabled.

Enter RIP view rip -
Set the default cost for
RIP to import routes from
other protocols default cost value Optional
When you use the
import-route command
without specifying the cost
of imported routes, the
default cost you set here
will be used.
