Table 1-2 Multicast protocols
Applied Location Objectives Multicast Protocol
Between hosts and
multicast switches
Connecting hosts to a multicast
network:
l Ensure that the members can
dynamically join and leave a
group at the host side.
l Manage and maintain the
member relationship at the switch
side and exchange information
with the upper-layer multicast
routing protocols.
Internet Group
Management Protocol
(IGMP)
Between intra-domain
multicast switches
Multicast routing and forwarding:
l Create multicast routes on
demand.
l Respond to the changes of the
network topology and maintain
the multicast routing table.
l Forward packets according to the
routing table.
Protocol Independent
Multicast (PIM), including
Protocol Independent
Multicast-Dense Mode
(PIM-DM) and Protocol
Independent Multicast-
Sparse Mode (PIM-SM)
Between inter-domain
multicast switches
Sharing information about inter-
domain multicast sources:
l Switches in the domain where the
source resides transmit the local
source information to switches in
other domains.
l Switches in different domains
transmit the source information.
Multicast Source
Discovery Protocol
(MSDP)
1.3.3 Typical Configuration Solution
CAUTION
Customize configuration solutions according to the actual network conditions and service
requirements. The configuration solution in this section functions only as a reference.
The network environments are classified into two types, which need different configuration
solutions. For details, refer to the Quidway S7700 Smart Routing Switch Configuration Guide
- Multicast.
NOTE
Ensure that unicast routes work normally in the network before configuring IP multicast.
