the packet, and forwards the request packet via unicast to the previous hop for the given multicast
source and group.
3) From the last-hop router to the multicast source, each hop adds a response data block to the end of
the request packet and unicasts it to the previous hop.
4) When the first-hop router receives the request packet, it changes the packet type to indicate a
response packet, and then sends the completed packet via unicast to the multicast traceroute
querier.

Complete these tasks to configure multicast routing and forwarding:

Enabling IP Multicast Routing

Configuring Multicast
Routing and Forwarding
IP multicast does not support the use of secondary IP address segments. Namely, multicast can be
routed and forwarded only through primary IP addresses, rather than secondary addresses, even if
configured on interfaces.
For details about primary and secondary IP addresses, refer to IP Addressing Configuration in the IP
Services Volume.
Enabling IP Multicast Routing
