Implementing Multicast Routing on Cisco IOS XR Software
Purpose
The MDT source interface name should be the same as
Note
the one used for BGP peerings.
Enables multicast routing and forwarding on all new and existing
interfaces. You can also enable individual interfaces.
Caution To avoid any possibility of a reverse-path forwarding
(RPF) failure, you should proactively enable any
interfaces that might possibly carry multicast traffic.
(Optional—IPv6 MVPN configuration only) Enters
address-family ipv6 configuration submode.
If you want to enable nonstop forwarding (NSF) for
Note
IPv6 VRFs, it requires global IPv6 configuration,
because NSF is available only there.
(Optional—IPv6 MVPN configuration only) Enables multicast
routing and forwarding on all new and existing interfaces. You
can also enable individual interfaces.
To avoid any possibility of a reverse-path forwarding
Caution
(RPF) failure, you should proactively enable any
interfaces that might possibly carry multicast traffic.
Configures a VPN routing and forwarding (VRF) instance and
enters VRF configuration mode.
Specifies the virtual routing and forwarding instance for the ipv4
address family.
Specifies the multicast distribution tree (MDT) default group
address.
Note Both IPv4 and IPv6 address families of the same vrf
should have the same MDT group address.
(IPv4 MVPN configuration only) Specifies the multicast group
address range to be used for data MDT traffic.
This group range should not overlap the MDT default
Note
group.
This is an optional command. The default threshold beyond
which traffic is sent using a data MDT group is 1 kbps. However,
you may configure a higher threshold, if desired.
