Hi Group,
I have problems in IE lab.4, task 7.8 - 7.9:
Can ping the multicast groups on R3 (225.25.25.25 and 239.39.39.39) from R2
but can't ping it from SW2
It was stated that multicast static routes are permitted but wasn't used in
the solution at all and I don't know if it could help !!
Output for show commands on R2, R3 and SW2 are as follows:
R3:
