Cisco Cisco IOS Software Release 12.2(33)SRE

If a BGP topology configuration is required, proceed to 

Perform this task to activate an MTR topology inside an address family using BGP. This task is 
configured on Router B in 

 and must also be configured on Router D and Router E. In this task, 

a scope hierarchy is configured to apply globally and a neighbor is configured under router scope 
configuration mode. Under the IPv4 unicast address family, an MTR topology that applies to video 
traffic is activated for the specified neighbor. There is no interface configuration mode for BGP 
topologies.

[transition] [level-1 | 

 | level-1-2]

Router(config-router)# metric-style wide 

Globally changes the metric value for all IS-IS interfaces. 

Wide style metrics are required for prefix tagging. 

[multicast | unicast]

Router(config-router)# address-family ipv4 

Enters router address family configuration mode under 
IS-IS router configuration mode.

topology-name tid number

Router(config-router-af)# topology DATA tid 100

Configures IS-IS support for the topology and assigns a TID 
number for each topology.

IS-IS support for the DATA topology is configured.

Router(config-router-topology)# end 

Exits router address family configuration mode and enters 
privileged EXEC mode.

Router# show isis neighbors detail

(Optional) Displays information about IS-IS neighbors.

This command has been modified to display MTR 
information for the TID values for the router and its 
IS-IS neighbors.
