Table 8-13 Trace the transmission path of an SA message over the network
Operation Command Description
Trace the
transmission
path of an
SA message
over the
network
msdp-tracert source-address
group-address rp-address
[ max-hops max-hops ]
[ next-hop-info | sa-info |
peer-info ]* [ skip-hops
skip-hops ]
You can execute the display
command in any view.
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.
8.6 MSDP Configuration Example
8.6.1 Configuration Example of Anycast RP Application
I. 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.
The PIM-SM network implements OSPF to provide unicast routes and establish MSDP
peers between SwitchC and SwitchD. Meanwhile, the Loopback10 interfaces of
SwitchC and SwitchD play the roles of C-BSR and C-RP.
