Configuring Multitopology Routing: Example

The following example shows the configuration required to enable a dual multicast topology. The two
topologies defined are named BLUE and GREEN. Each contains one interface. IS-IS is configured so
that each interface is only in the IS-IS topology, and the interfaces themselves are configured so that their
connected and local routes are placed only within the appropriate routing tables.
The routing policy was configured to select which topology should be used based on the source address
of the multicast flow.
