Is it a lab requirement to use this ACL? If not change your ACL to:

access-list 10 permit 225.10.0.0 0.0.255.255
access-list 10 permit 225.26.0.0 0.0.255.255
access-list 10 permit 225.42.0.0 0.0.255.255
access-list 10 permit 225.58.0.0 0.0.255.255

Hello Brian,

I am trying to match
225.10.0.0 - 225.10.255.255
225.26.0.0 - 255.26.255.255
225.42.0.0 - 255.42.255.255
225.58.0.0 - 255.58.255.255

But when I join a Multicast Group on Sw1 (like

Rack1Sw1#show ip igmp gr
IGMP Connected Group Membership
Group Address Interface Uptime Expires Last Reporter
225.11.11.11 FastEthernet0/4 00:14:35 00:02:24 164.1.47.7
224.0.1.40 FastEthernet0/4 04:06:30 00:02:22 164.1.47.7

and on R2 I do ping to that group ..

Rack1R2#ping 225.11.11.11

Type escape sequence to abort.
Sending 1, 100-byte ICMP Echos to 225.11.11.11, timeout is 2 seconds:

Reply to request 0 from 164.1.47.7, 225 ms
Rack1R2#

But in R3 is marked at the mcast table as Sparse.. That group should be Dense right??

ip pim send-rp-announce Loopback0 scope 16 group-list 10
ip pim send-rp-discovery Loopback0 scope 16
Rack1R3#show access-list 10
Standard IP access list 10
    10 permit 225.10.0.0, wildcard bits 0.48.255.255
