I am currently planning a new datacenter and all that entails. This datacenter is in the same city and is less than 2ms latency. The old datacenter and new datacenter will be connected with a VPLS circuit terminated on CISCO ISRs. The datacenter use vmware and all machines need to be vmotioned to the new datacenter.
Each datacenter has a pair of Nexus switches hosting the layer 3 datacenter networks configured with HSRP on each DC.
HSRP requires layer 2 connectivity to properly share the HSRP packets. Since the VPLS is terminated on an ISR, the packets do not flow between the 2 sites and they do not share a floating IP.
Is there a method to setup a HSRP style network between these 2 datacenters to allow easy migration without giving new IPs to the workloads?
