Hello,
Where is the 0100.5e01.0101 address?
"sh mac-address-table multicast"
is empty?
I have a scenario where I would like to check the mapped multicast
mac-address for a multicast group and I thought I could do that after enabling
the ip igmp join-group 224.1.1.1 on a SVI or connected router interfaces to
the switch ports.
I have attached 4 routers and 2 of then are simulating
receivers and the other two are just there to make me believe in the igmp
snooping ie that it does not flood the non receiver ports. All "hosts" are
connected to the same vlan.
xxxxxxxxxxxxxxxxxxxxxxx
sw4#sh mac-address-table
multicast
Vlan Mac Address Type Ports
---- -----------
---- -----
<-- I expected to have something here ie the mapped 224.1.1.1 -->
0100.5e01.0101
sw4#
xxxxxxxxxxxxxxxxxxxxxxx
I created a static entry and that
show up???
sw4#sh mac-address-table multicast
Vlan Mac Address Type
Ports
---- ----------- ---- -----
100 0100.5e00.1234
USER Gi0/23
sw4#
xxxxxxxxxxxxxxxxxxxxxxx
This is one of the routers
simulating a receiver connected to sw4:
FRS#sh ip igmp groups 224.1.1.1
IGMP
Connected Group Membership
Group Address Interface Uptime
Expires Last Reporter
224.1.1.1 FastEthernet0/0 01:05:10
00:02:03 150.1.56.10
FRS#
Does anyone have a small test scenario I could test
so I actually can see the dynamic multicast mac-address entry that I though
igmp snooping would do or what am I missing?
Best Regards,
Sydney
