Guidelines For Enabling The Vlt Proxy Gateway - Dell Z9000 Configuration Manual

Guidelines for Enabling the VLT Proxy Gateway

Keep the following points in mind when you enable this functionality:
1. The proxy gateway is supported only for VLT; for example, across VLT domain.
2. You must enable the VLT peer-routing command for the VLT proxy gateway to function.
3. The current design does not handle asymmetric virtual local area network (VLAN) configuration
scenarios such as the same VLAN configured with L2 mode on one VLT domain and L3 mode on
another VLT domain. You must always configure the same mode for the VLANs across the VLT
domain.
4. You must maintain VLAN symmetry within a VLT domain.
5. The connection between DCs can only be a L3 VLT in eVLT format . For more information, refer to
the eVLT Configuration Example
6. Trace route across DCs may show extra hops.
7. You must maintain route symmetry across the VLT domains to ensure no traffic drops. When the
routing table across DCs is not symmetrical, there is a possibility of a routing miss by a DC that does
not have the route for the L3 traffic. Because routing protocols are enabled and both DCs come in
