DVMRP

• Distance Vector Multicast Routing Protocol

• RFC 1075

• A distance vector type of multicast routing protocol

• DVMRP constructs delivery trees based on the information

on the previous-hop back toward the source.

(5)

DVMRP

• The distribution tree provides a shortest path between the

source and receiver in the group, based on the number of

hops in the path.

• The one that is closest to the source of a multicast message

is elected to be in charge of forwarding multicast messages.

• With the same distance from the source, the router with the

lowest IP address is elected.

6. Commands for checking the multicast groups. sh ipmc cache

sh igmp group

At Multicast Server

1. Manually configure IP address, mask, for the associated IP Network

2. Install and run the Multicast Server program, for example, CISCO IPTV Server or Microsoft’s Media Server.

3. Play the video program using “multicast”

At Client PC

1. Manually configure IP address, mask, for the associated IP Network.Interface IP. 2. Install and run the Multicast client software, for example, CISCO IPTV viewer or

Microsoft IE/MediaPlayer.

PIM-DM

• PIM - Protocol Independent Multicast

• PIM contains two protocols: PIM – Dense Mode

(PIM-DM), and PIM – Sparse Mode (PIM-SM)

• PIM-DM is similar to DVMRP for forming delivery trees

• PIM-DM also forwards multicast messages on all

downstream interfaces until it receives prune messages,

while DVMRP forwards multicast traffic to child nodes in

the delivery tree.
