According to cisco document "IPv4 multicast MAC addresses from 0100.5E00.0000 to 0100.5EFE.FFFF" are allowed . eigrp multicast address is 22.214.171.124 . for this mac address will be in previous mac address's. so why we have to open manualyl access-list for eigrp multicast from
inside to outside and outside to inside ????? same case happen for rip v2 .
