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 ASR 9000 Series Aggregation Services Router Routing Configuration Guide.
• “Enabling an IS-IS Topology” (required)
For information, see Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide.
• “Placing an Interface in a Topology in IS-IS” (required)
For information, see Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide.
• “Configuring a Routing Policy” (required)
