Cisco Cisco IOS Software Release 12.2(33)SRE

The following example shows how to configure an access list to be used by a route map named BLUE 
to filter routes imported from the MTR topology named VOICE. Only routes with the prefix 192.168.1.0 
are imported. 

access-list 1 permit 192.168.1.0 0.0.0.255 

route-map BLUE

match ip address 1

exit

router bgp 50000 

scope global

neighbor 10.1.1.2 remote-as 50000

neighbor 172.16.1.1 remote-as 60000

address-family ipv4 

topology VIDEO 

bgp tid 100

neighbor 10.1.1.2 activate 

neighbor 172.16.1.1 activate 

import topology VOICE route-map BLUE 

end

clear ip bgp topology VIDEO 50000 

The following example disables the VOICE topology on Ethernet interface 0/0. 

interface Ethernet 0/0

 topology ipv4 VOICE disable

The following example disables OSPF routing on interface Ethernet 0/0 without removing the interface 
from the global topology configuration: 

interface Ethernet 0/0

 topology ipv4 VOICE

  ip ospf cost 100

  ip ospf topology disable

end 

In the following example, the show ip ospf interface command is used with the topology keyword to 
display information about the topologies configured for OSPF in interface configuration mode.

Router# show ip ospf 1 interface topology VOICE
