View TLV Information for Layer 2 VSN IP Multicast over Fabric Connect

Use the following commands to check TLV information.

For Layer 2 VSN with IP multicast over Fabric Connect, TLV 185 on the BEB where the source is located, displays the multicast source and group addresses and has the Tx bit set. Each multicast group has its own unique data I-SID with a value between 16,000,000 to 16,512,000. TLV 144 on the BEB bridge, where the sender is located, has the Tx bit set. All BEB bridges, where a receiver exists, have the Rx bit set.

Procedure

To enter User EXEC mode, log on to the switch.
Display IS-IS Link State Database information by Type-Length-Value (TLV):

show isis lsdb tlv <1–236> [sub-tlv <1–3>] [detail] [home|remote]
Display IS-IS Link State Database information by Link State Protocol ID:

show isis lsdb lspid <xxxx.xxxx.xxxx.xx-xx> tlv <1–236> [sub-tlv <1–3>] [detail] [home|remote]

Example

Switch:1# show isis lsdb tlv 185 detail
