Usage guidelines
A router might receive many host routes from the same subnet. These routes are not helpful for routing and
occupy many resources. To solve this problem, use the undo host-route command to disable RIP from
receiving host routes.
This command takes effect only for RIPv2 routes.
Examples
# Disable RIP from receiving host routes.
<Sysname> system-view
[Sysname] rip 1
[Sysname-rip-1] undo host-route
import-route
Use import-route to enable route redistribution from another routing protocol.
Use undo import-route to disable route redistribution.
Syntax
import-route protocol [ process-id | all-processes | allow-ibgp ] [ cost cost | route-policy
route-policy-name | tag tag ] *
undo import-route protocol [ process-id | all-processes ]
Default
RIP does not redistribute routes from any other routing protocol.
Views

Parameters
protocol: Specifies a routing protocol from which RIP redistributes routes. It can be bgp, direct, isis, ospf,
rip, or static.
process-id: Specifies a process by its ID in the range of 1 to 65535. The default is 1. This argument is
available only when the protocol is isis, rip, or ospf.
all-processes: Enables route redistribution from all the processes of the specified protocol. This keyword
takes effect only when the protocol is rip, ospf, or isis.
allow-ibgp: Allows redistribution of IBGP routes. This keyword is available when the protocol argument
is set to bgp.
cost cost: Specifies a cost for redistributed routes, in the range of 0 to 16. The default cost is 0.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters.
tag tag: Specifies a tag for marking redistributed routes, in the range of 0 to 65535. The default is 0.
