SPB Multicast Configuration
20.1.21.1 L2VSN Multicast
Enabling SPM Multicast
config terminal
router isis
spbm 1 multicast enable
exit
interface vlan <vlan id>
ip igmp snoop
ip igmp snoop-querier-addr <ip addr>
ip igmp ssm-snoop **If IGMPv3 is required
ip igmp version 3 **If IGMPv3 is required
exit
ERS 4800 & ERS 5900:
config terminal
router isis
spbm 1 multicast enable
exit
interface vlan <vlan id>
ip igmp snooping
ip igmp snoop-querier-addr <ip addr>
ip igmp version 3 **If IGMPv3 is required
exit
For multicast over L2VSN’s, please note if the SPB bridge is connected to an edge switch, it may
be necessary to add an IGMP query address. If you omit adding a query address, the SPB bridge
will send IGMP queries with a source address of 0.0.0.0. Depending on the edge switch model, it
may not accept a query with a source address of 0.0.0.0. This is the case if using an Extreme
stackable edge switch that supports IGMPv3.
Verify Operations:
show isis spbm (verify multicast is enabled)
show ip igmp interface
show isis spbm ip-multicast-route all
show isis spbm ip-multicast-route vsn-isid <ISID value>
show isis lsdb tlv 185 detail
show isis lsdb sysid <system id> tlv 185 detail
show ip igmp sender
The following commands can be performed on receiving BEB nodes:
show ip igmp cache
show ip igmp group
The following commands can be performed on sending BEB node:
l2 tracemroute source <ip addr of source> group <group ip address> vlan <C-VLAN id>
