Multicast Grouping
Mike,
Write them in binary. 226 - 1110 0010 12 - 0000 1100
The possible combinations would be: 1110 0010 - 226 1110 0110 - 230 1110 1010 - 234 1110 1110 - 238
So by having a mask of 12 you are are matching only above 4 addresses.
HTH, Shine

Hello,
I still don’t understand why the below ACL can’t be grouped: interface Loopback0 ip pim sparse-dense-mode ! ip pim send-rp-announce Loopback0 scope 16 group-list 50 ! access-list 50 permit 226.0.0.0 1.255.255.255 access-list 50 permit 228.0.0.0 3.255.255.255 access-list 50 permit 232.0.0.0 3.255.255.255 access-list 50 permit 236.0.0.0 1.255.255.255 access-list 50 permit 238.0.0.0 0.255.255.255
Why can’t we group them as: access-list 50 permit 226.0.0.0 12.255.255.255
Thanks for the clarification,
