LLDP VLT Proxy Gateway in a Square VLT Topology

Figure 145. Sample Configuration for a VLT Proxy Gateway
• The preceding figure shows a sample square VLT Proxy gateway topology. 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. 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.
Sample Configuration
Dell(conf-vlt-domain)#proxy-gateway lldp
Dell(conf-vlt-domain-pxy-gw-lldp)#vlt-peer-mac transmit
• Assume the inter-chassis link (ICL) between C1 and D1 is shutdown and if D1 is the secondary VLT, one half of the inter DC link goes
down. After VM motion, if a packet reaches D1 with the destination MAC address of D, it may be dropped. This behavior is applicable
only in an LLDP configuration; in a static configuration, the packet is forwarded.
