Dell S4048T User Manual

For more information about eVLT, refer to the Virtual Link Trunking (VLT) chapter. The core or Layer 3 routers
C and D in local VLT Domain and C1 and D1 in the remote VLT Domain are then part of a Layer 3 cloud.
Figure 137. Sample Configuration for a VLT Proxy Gateway
Guidelines for Enabling the VLT Proxy Gateway
Keep the following points in mind when you enable a VLT proxy gateway:
• Proxy gateway is supported only for VLT; for example, across a VLT domain.
• You must enable the VLT peer-routing command for the VLT proxy gateway to function.
• Asymmetric virtual local area network (VLAN) configuration, such as the same VLAN configured with
Layer 2 (L2) mode on one VLT domain and L3 mode on another VLT domain is not supported. You must
always configure the same mode for the VLANs across the VLT domain.
• You must maintain VLAN symmetry within a VLT domain.
