Information About LISP Host Mobility Across Subnet
Devices configured with LISP Host Mobility ASM have the following characteristics:
Each edge router (xTR) is the first Layer-3 hop
Proxy-arp is enabled on the xTR's gateway interface
Each roaming site xTR should register with a common set of map-servers
Mobility hosts should not be "silent" after they move
A multicast configuration is needed by xTRs only if the site has multiple xTRs, for example for HSRP. A single xTR does not need to use multicasting.
Supports vmotion or live host mobility only in the case of North-South traffic
LISP encapsulation (ASM) is required for East-West traffic.
You can use LISP Host Mobility Across Subnet commands to deploy extended subnets and across subnets. A detailed configuration guide and examples are under development and will appear here soon. Meanwhile, please refer to the LISP Command Reference.
