22.5.3.5 Trace Multicast Routes
On the switch where the multicast sender is located, in our example this would be switch 8007, you can
trace the multicast route by specifying the source, group, and VLAN.
Step 1 – Verify all SPB multicast routes
l2 tracemroute source <source address> group <group address> vlan <C-VLAN id>
Results: Since the multicast source is via bridges 8005 & 8006, we will use the following
command to view the multicast route for group address 232.2.2.2
8005:3#
l2 tracemroute source 10.5.41.20 group 232.2.2.2 vlan 2256
Please wait for l2tracemroute to complete or press any key to abort
Source : 10.5.41.20
Group : 232.2.2.2
VLAN : 2256
BMAC : 03:08:05:f4:24:03
B-VLAN : 4051
ISID : 16000003
