Quidway S5600 Series Ethernet Switches-Release 1510 Chapter 8 MSDP Configuration
Huawei Technologies Proprietary
8-12
Generally, a router accepts all SA messages sent by all MSDP peers and sends all SA
messages to all MSDP peers. By configuring the rules for filtering SA messages to
receive/send, you can effectively control the transmission of SA messages among
MSDP peers. For forwarded SA messages, you can also configure a Time-to-Live (TTL)
threshold to control the range where SA messages carrying encapsulated data are
transmitted.
To reduce the delay in obtaining the multicast source information, you can cache SA
messages on the router. The number of SA messages cached must not exceed the
system limit. The more messages cached, the more router memory occupied.
8.4.1 Configuration Prerequisites
Before you configure SA message transmission, perform the following tasks:
z Configuring a unicast routing protocol.
z Configuring basic IP multicast functions.
z Configuring basic PIM-SM functions.
z Configuring basic MSDP functions.

8.4.2 Configuring the Transmission and Filtering of SA Request Messages
After you enable sending SA request messages, when a router receives a Join
message, it sends an SA request message to the specified remote MSDP peer, which
responds with an SA message that it has cached. After sending an SA request
message, the router will get immediately a response from all active multicast sources.
By default, the router does not send an SA request message to its MSDP peers upon
receipt of a Join message; instead, it waits for the next SA message..
