The EIGRP multicast address 224.0.0.10 maps to MAC address 0100.5e00.000a.
You are flooding the EIGRP multicasts only out of the specified switch
ports, effectively keeping BB3 from receiving the traffic. You must disable
IGMP snooping for the VLAN before the static MAC address table entry can be
entered.
