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
Follow these steps to trace the transmission path of an SA message over the network:
To do...
Trace the transmission path
of an SA message over the
network
Trace the transmission path
of messages sent by the
multicast source 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.

MSDP Configuration Example

Anycast RP Configuration

Network requirements
The PIM-SM domain has multiple multicast sources and receivers. OSPF runs within the domain to
provide unicast routes.
It is required to configure the anycast RP feature so that the receiver-side DRs and the source-side
DRs can initiate a Join message to their respective RPs that are the topologically nearest to them.
On Switch B and Switch D, configure the interface Loopback 10 as a C-BSR, and Loopback 20 as
a C-RP.
The router ID of Switch B is 1.1.1.1, while the router ID of Switch D is 2.2.2.2. Set up an MSDP
peering relationship between Switch B and Switch D.
To do...
msdp-tracert source-address
group-address rp-address [ max-hops
max-hops ] [ next-hop-info | sa-info |
peer-info ]* [ skip-hops skip-hops ]
mtracert source-address [ group-address |
last-hop-router-address group-address ]
Use the command...
display msdp sa-cache
[ group-address | source-address
| as-number ] *
display msdp sa-count
[autonomous-system-number ]
reset msdp peer peer-address
reset msdp sa-cache
[ group-address ]
reset msdp statistics
[ peer-address ]
