282 CHAPTER 33: RIP CONFIGURATION
Configuring RIP to import routes from another protocol
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
Configuration Tasks Configuring RIP timers
Tabl e 205 Configure RIP to import routes from another protocol
Operation Command Description
Enter system view system-view -
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.
Configure RIP to import
routes from another protocol
import-route protocol [
process-id ][ cost value |
allow-ibgp | route-policy
route-policy-name ]*
Optional
The allow-ibgp parameter is
used only for importing BGP
routes.
The process-id parameter is
used only for importing OSPF
routes.
Tabl e 206 Configure RIP timers
Operation Command Description
Enter system view system-view -
Enter RIP view rip -
Set the values of RIP timers
timers { update update-timer
| timeout timeout-timer } *
Optional
By default, Update timer value
is 30 seconds and Timeout
timer value is 180 seconds.
