Routers A and B run RIP with each other, and Routers A and C run BGP with each
other. If you want Router A to redistribute routes from 170.10.0.0 with a metric of 2 and to
redistribute all other routes with a metric of 5, use the following commands for Router A:

!Router A
router rip
network 3.0.0.0
network 2.0.0.0
network 150.10.0.0
passive-interface serial 0
redistribute bgp 100 route-map SETMETRIC
!
router bgp 100
neighbor 2.2.2.3 remote-as 300
network 150.10.0.0
!
route-map SETMETRIC permit 10
match ip-address 1
set metric 2
!
route-map SETMETRIC permit 20
set metric 5
!
access-list 1 permit 170.10.0.0 0.0.255.255

When a route matches the IP address 170.10.0.0, it is redistributed with a metric of 2. When a route does not match the IP address 170.10.0.0, its metric is set to 5, and the route is redistributed.Assume that on Router C you want to set to 300 the community attribute of outgoing updates for network 170.10.0.0. The following commands apply a route map to outgoing updates on Router C:

!Router C
router bgp 300
network 170.10.0.0
neighbor 2.2.2.2 remote-as 100
neighbor 2.2.2.2 route-map SETCOMMUNITY out
!
route-map SETCOMMUNITY permit 10
match ip address 1
set community 300
!
access-list 1 permit 0.0.0.0 255.255.255.255

 

Access list 1 denies any update for network 170.10.0.0 and permits updates for any other network.
