Table 652 Configure SA message cache (continued)
Operation
Configure the maximum
number of SA messages
cached
After the above-mentioned configuration, you can use the display command in any
view to view the MSDP running information, so as to verify configuration result.
In the user view, you can execute the reset command to reset the MSDP counter.
Table 653 Display and debug MSDP configuration
Operation
Display the brief information of MSDP peer
state
Display the detailed information of MSDP peer
state
Display the (S, G) state learned from MSDP
peers
Display the number of sources and groups in
the MSDP cache
Reset the TCP connection with the specified
MSDP peer
Clear the cached SA messages
Clear the statistics information of the specified
MSDP peer without resetting the MSDP peer
Tracing the transmission path of an SA message over the network
You can use the msdp-tracert command in any view to trace the path along which
the multicast data travels from the multicast source to the destination receiver over
the network, so as to locate errors, if any.
Table 654 Trace the transmission path of an SA message over the network
Operation
Trace the transmission
path of an SA message
over the network
You can locate message loss and configuration errors by tracing the network path of
the specified (S, G, RP) entries. Once the transmission path of SA messages is
determined, correct configuration can prevent the flooding of SA messages.
This section contains an MSDP configuration example.
Network requirements
Each PIM-SM network is a single-BSR administrative domain, with multiple multicast
sources (S) and receivers. With Anycast RP configured in each PIM-SM domain, when
a new member joins the multicast group, the switch directly connected to the receiver
can send a Join message to the nearest RP on the topology.
