Instead of proxy gateway, you can use VRRP in access VLAN to migrate virtual machines across data centers. You must assign same VRRP group IDs to the VLANS, with VRRP in active-active mode. The following illustration shows a sample configuration with two data centers: • Server racks, Rack 1 and Rack 2, are part of data centers DC1 and DC2, respectively. • Rack 1 is connected to devices A1 and B1 in a Layer 2 network segment. • Rack 2 is connected to devices A2 and B2 in a Layer 2 network segment. • A VLT link aggregation group (LAG) is present between A1 and B1 as well as A2 and B2. • A1 and B1 are connected to core routers, C1 and D1 with VLT routing enabled. • A2 and B2 are connected to core routers, C2 and D2, with VLT routing enabled. • The core routers C1 and D1 in the local VLT domain are connected to the core routers C2 and D2 in the remote VLT Domain using VLT links. • The core routers C1 and D1 in local VLT Domain along with C2 and D2 in the remote VLT Domain are part of a Layer 3 cloud. • The core routers C1, D1, C2, D2 are in a VRRP group with the same vrrp-group ID.
