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:
