Perform the following configuration in routing protocol view.

Define a policy rule to filter unqualified routing information during route reception 
by importing an ACL or IP-prefix. The keyword parameter gateway indicates only 
update packets from specific peer routers will be received.

Define a policy concerning route distribution to filter the routing information not 
satisfying the conditions while importing routes by importing an ACL or address 
ip-prefix list. Filter routing information only about the distributed routing-process 
by specifying routing-process.

Perform the following configuration in routing protocol view.

By far, the route policy supports importing the routes discovered by the following 
protocols into the routing table:

■

direct: The hop (or host) to which the local interface is directly connected.

■

static: Static route.

■

rip: Route discovered by RIP.

■

ospf: Route discovered by OSPF.

■

ospf-ase: External route discovered by OSPF.

■

ospf-nssa: NSSA route discovered by OSPF.

■

isis: Route discovered by IS-IS.

■

bgp: Route acquired by BGP.

Table 677   Configuring to filter the imported routes

Configure to filter the received 
routing information imported by 
the specified address

filter-policy gateway ip-prefix-name 
import

Cancel the filtering of the 
received routing information 
imported by the specified address

undo filter-policy gateway ip-prefix-name 
import

Configure to filter the received 
global routing information

filter-policy { acl-number | ip-prefix 
ip-prefix-name } [ gateway ] import

Cancel the filtering of the 
received routing information

undo filter-policy { acl-number | 
ip-prefix ip-prefix-name } [ gateway ] 
import

Table 678   Configuring to filter the distributed routes

Configure to filter the routes 
distributed by the protocol

filter-policy { acl-number | ip-prefix 
ip-prefix-name } export [ routing-process ]

Cancel the filtering of the 
routes distributed by the 
protocol

undo filter-policy { acl-number | ip-prefix 
ip-prefix-name } export [ routing-process ]
