The LLDP organizational TLV passes local destination MAC address information to peer VLT domain devices so they can act as the proxy
gateway. Two congurations are required to enable Proxy Gateway LLDP:
• Global proxy gateway LLDP conguration to enable this feature
• Interface proxy gateway LLDP conguration to enable/disable proxy-gateway LLDP TLV on particular interfaces
• The interface is typically a VLT port-channel which connects to a remote VLT domain
• The new proxy gateway TLV is carried on the physical links under the port channel only
• There should be at least one link connection to each unit of the VLT domain
Following are the prerequisites for Proxy Gateway LLDP conguration:
• LLDP must be globally enabled
• No interface– level LLDP disable CLIs on the interfaces congured for proxy gateway, and you must enable both transmission and
reception
• You must connect both units of the remote VLT domain by the port channel member.
• If you connect more than one port to a unit of the remote VLT domain, it must be completed by the time you enable the proxy gateway
LLDP
• You cannot have other conicting congurations (for example, the no static proxy gateway conguration)
This feature might not operate properly if one of the following conditions is true:
• Any proxy gateway conguration or LLDP conguration is not working
• LLDP packets fail to reach the remote VLT domain devices (due to system down, rebooting, port down or physical link connection)
Sample Congurations for LLDP VLT Proxy Gateway
Apply the following congurations in the Core L3 Routers C and D in the local VLT domain and C1 and D1 in the remote VLT domain:
1 Congure proxy-gateway lldp in VLT Domain CONFIG mode.
2 Congure peer-domain-link port-channel <vlt portchannel ID> in VLT Domain Proxy Gateway LLDP mode. The
VLT port channel is the one that connects the remote VLT domain.
Sample Congurations for Static VLT Proxy Gateway
Apply the following congurations in the Core L3 Routers C and D in local VLT domain and C1 and D1 in the remote VLT domain:
1 Congure proxy-gateway static in VLT Domain CONFIG mode
2 Congure remote-mac-address <mac-address> in VLT Domain Proxy Gateway LLDP mode. Congure the system mac-
addresses of both C and D in C1 and also in D1 in the remote VLT domain and vice versa.
