I am looking for an advice and was hoping someone would give / guide me the right directions
we have two nexus 7009 configured together with vPC and Peer-Link , working just fine.
now we are planning in our design to connect our WAN router facing the MPLS side to connect directly to both nexus for high-availability
there are two ways
#1. Have the router two physical interfaces connect to both N7K with different ip subnet addresses. (which leaves me in a puzzle that which interface the router will use to send the traffic and to which N7K
#2. Configure HSRP between both N7K and have the router talk to the VIP to be able to communicate to which ever N7K is Active (for this part , how will I connect the router physically and how will the router communicate to the N7K
Lastly does it mean make any difference in doing above because both NEXUS are connected via vPC and Peer-Link is working.
Thanks In Advance
