The objective of this lab is to use 2 separate routers R2 and R4 for the RPs for different multicast groups, 224.0.0.0/5 and 232.0.0.0/5, respectively. The task also designates only 1 Mapping Agent.
The configuration is the same as the last lab, lab 4, except for designating a group-list on the RPs.
I stumbled when creating the ACL for the group list, instead of using the wild card mask 7.255.255.255, used 31.255.255.255. I should have just done it the right way 8 bits minus 5 bits is 3 bits. 3 bits in decimal is 7.
Configs:
R2 - RP for 224.0.0.0/5
!
ip pim send-rp-announce Loopback0 scope 16 group-list 1
!
logging alarm informational
access-list 1 permit 224.0.0.0 7.255.255.255
R4 - RP for 232.0.0.0/5
ip pim send-rp-announce Loopback0 scope 16 group-list 1
!
logging alarm informational
access-list 1 permit 232.0.0.0 7.255.255.255
