Charles,
I understood partially. Follow my understanding:
1) In fact that MAC Address is the MAC address of EIGRP announcements
(converted from IP 224.0.0.10 to MAC 0100.5e00.000a).
2) Look that the ACL applied in the BB3 port is in the inbound direction, so
the switch don't accept EIGRP packets from BB3.
3) The static MAC entries are to permit that the EIGRP frames to be sent
just between R1, R3 and R6. This command resolves the "outbound direction
problem" (in other words, EIGRP frames aren't sent to the BB3 port).
So, if the inbound and outbound direction problem are resolved, I didn't
understand for what reason the IGMP Snooping command was used.
Tks,
Fabio.
