CISCO LISP

LISP

How does Lisp deal with a situation in which you have two DC connected via OTV hence sharing the same Layer 2 network and VM's are vmotioned from one DC to the other DC.  The IP info does not change but the location changes.

Does the Lisp router at the second site advertise individual host routes or can only one DC be active at a time???/

LISP would handle the IP prefix location identification piece. So in this scenario you vmotion servers from data center 1 to datacenter 2. Each have their own internet connectivity, so how does an endpoint know how to route traffic to the correct datacenter without sub-optimal routing? Vmotion changed the location of the servers but external routing has not been updated to reflect the change so sub-optimal routing occurs. LISP achieves this by adding LISP EID-to-RLOC mapping services.

EID = Endpoint indentifier
RLOC = Routing Locator
