Implementing Layer-3 Multicast Routing on Cisco IOS XR Software
Purpose
group. Traffic from groups not on the access-list continues
to be tunneled using the default MDT group.
This is an optional step.
Specifies the MTU size. It is recommended to configure a
high value, to accommodate the maximum multicast packet
size.
The default MTU for PIM/GRE MDT is 1376 and
Note
the default value for mLDP/P2MP-TE MDT is
9000 for Multicast VPN.
Enables multicast routing and forwarding on all new and
existing interfaces.
Purpose
Enters PIM address-family configuration submode and
configures the PIM VRF for either an IPv4 or IPv6 address
family.
