Cisco CRS Series - Configuring an RPF Topology in PIM; Information about Multitopology Routing

◦
Open Shortest Path First (OSPF)
◦
Intermediate System-to-Intermediate System (IS-IS)
◦
Multiprotocol Border Gateway Protocol (MBGP)
Although both multicast and unicast keywords are available when using the address-family {ipv4 |
ipv6} command in routing policy language (RPL), only topologies under multicast SAFI can be configured
globally.
Note
Information About Multitopology Routing
Configuring multitopology networks requires the following tasks:
• “Configuring a Global Topology and Associating It with an Interface” (required)
For information, see Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router.
• “Enabling an IS-IS Topology” (required)
For information, see Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router.
• “Placing an Interface in a Topology in IS-IS” (required)
For information, see Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router.
• “Configuring a Routing Policy” (required)
For information, see Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router.
For an example of multitopology routing, see Configuring Multitopology Routing: Example, on page 159.
