IP Multicast Routing - Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs
3 important questions on IP Multicast Routing - Sparse-Mode Routing Protocols - Dynamically Finding RPs and Using Redundant RPs
What is the command to check which RP is used?
R2#show ip pim rp mapping
PIM Group-to-RP Mappings
Group(s): 220.127.116.11/4, Static
RP: 18.104.22.168 (?)
What is the advantage of using anycast RP? 2
-Fast recovery after failed RP
Why is MSDP necessary if anycast is used with two RP's?
join to a different RP, a method is needed for the RPs to exchange information about active sources. This information exchange is done with MSDP.
