Configuring Multitopology Routing
• To check the MPLS forwarding status, use show mpls forwarding command:
Configuring Multitopology Routing
This set of procedures configures multitopology routing, which is used by PIM for reverse-path forwarding
(RPF) path selection.
• "Configuring a Global Topology and Associating It with an Interface" (required)
• "Enabling an IS-IS Topology" (required)
• "Placing an Interface in a Topology in IS-IS" (required)
• "Configuring a Routing Policy" (required)
Restrictions for Configuring Multitopology Routing
• Only the default VRF is currently supported in a multitopology solution.
• Only protocol-independent multicast (PIM) and intermediate system-intermediate system (IS-IS) routing
• Topology selection is restricted solely to (S, G) route sources for both SM and SSM. Static and IS-IS

are the only interior gateway protocols (IGPs) that support multitopology deployment.
For non-(S, G) route sources like a rendezvous point or bootstrap router (BSR), or when a route policy
is not configured, the current policy default remains in effect. In other words, either a unicast-default or
multicast-default table is selected for all sources based on any of the following configurations:
