3Com 5500-EI PWR - Anycast Rp Configuration; Msdp Configuration Example

15
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
z The PIM-SM domain has multiple multicast sources and receivers. OSPF runs within the domain to
provide unicast routes.
z 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.
z On Switch B and Switch D, configure the interface Loopback 10 as a C-BSR, and Loopback 20 as
a C-RP.
z 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.
