Viewing TLV information for a Layer 3 VSN with IP Multicast over Fabric Connect

Use the following commands to check TLV information.

For a Layer 3 VSN multicast, TLV 185 on the BEB where the source is located displays the multicast source and group addresses and have the Tx bit set. Each multicast group should have 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 TLV:

show isis lsdb tlv <1–236> [sub-tlv <1–3>][detail]
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]
