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 To get full benets out of proxy gateway, peer-routing is recommended
3 The current design does not handle asymmetric virtual local area network (VLAN) conguration scenarios such as the same VLAN
congured with L2 mode on one VLT domain and L3 mode on another VLT domain. Congure 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 Conguration Example
6 Trace route across DCs may show extra hops.
7 You must maintain route symmetry across the VLT domains to ensure no trac 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 trac. Because routing protocols
are enabled and both DCs come in the same subnet, there is no route asymmetry dynamically. But if you congure the static route on
one DC and not on the other, there is asymmetry.
