MSDP speaker in a PIM-SM domain establishes MSDP peering ses-
sion with MSDP peers in other domains through TCP connection.
When MSDP speaker has learnt a new multicast source (through
the PIM register mechanism) in local domain, it creates a Source-
Active message and sends it to all the MSDP peers.
Each MSDP peer that receives the message uses peer-RPF check
and only the SA message received on correct interface is for-
warded, discarding the others. When an MSDP peer which is also
an RP for its own domain receives a new SA message and the
outgoing interface list in (*, G) entry is non-empty, that is, there
are receivers within the domain, RP creates a (S, G) state for
multicast source and adds this entry to the shortest-path tree of
the source.
In addition, each MSDP peer saves the received SA messages in a
cache, thus establishing a SA cache table. If the RP in a PIM-SM
domain receives a new PIM join message for multicast group G,
the RP searches its own SA cache table to get all the active mul-
ticast sources immediately, thus generating the corresponding (S,
G) Join message.

PIM-SNOOPING

PIM Snooping obtains the multicast routing port by snooping the
HELLO and JOIN/PRUNE messages of the multicast protocol and
forwards the multicast data as well as reduces network traffic.

Configuring IGMP Version

ZXR10 5900E IGMP function is based on PIM interface. All inter-
faces enabling PIM enables IGMP function automatically.

Configuring IGMP Version

At present the IGMP has the V1 and the V2. Default value is V2.
