• LLDP packets fail to reach the remote VLT domain devices (for example, because the system is down,
rebooting, or the port physical link connection is down).
Figure 138. Sample Configuration for a VLT Proxy Gateway
• The above figure shows a sample VLT Proxy gateway scenario. There are no diagonal links in the square
VLT connection between the C and D in VLT domain 1 and C1 and D1 in the VLT domain 2. This causes
sub-optimal routing with the VLT Proxy Gateway LLDP method. For VLT Proxy Gateway to work in this
scenario you must configure the VLT-peer-mac transmit command under VLT Domain Proxy
Gateway LLDP mode, in both C and D (VLT domain 1) and C1 and D1 (VLT domain 2). This behavior is
applicable only in the LLDP configuration and not required in the static configuration.
