Hi All

I have a case which says :

                  R4
                   | f0/0
                   |
             CLIENTS

These clients shd only recieve feeds for groups 225.25.25.25 and
226.26.26.26

I answered :

Rack1R4(config-if)#do sh ip access-li
Standard IP access list 17
    10 permit 225.25.25.25
    20 permit 226.26.26.26

int f0/0
 ip multicast boundary 17
!

2nd solution
---------------------
Let these clients join these 2 grps only

int f0/0
ip igmp access-grp 17
!

Let me know if and why sol 1 is wrong ?
