Use Case for LISP Local Extranet Policies

5. Creates a map-cache for the H2 EID prefix into IID 100 on xTR1 with the property that the traffic needs
to be encapsulated using IID 300.
6. Traffic from H1 to H2 is encapsulated using IID 300 based on the new map-cache.
7. xTR3 receives traffic with IID 300, decapsulates the traffic and forwards the packet to H2.
Use Case for LISP Local Extranet Policies
Another benefit of the LISP Extranets feature is that a user can provision dynamic local VRF Leaking support.
A user can specify an Extranet policy on the Mapping System (MS), which the LISP xTRs will apply locally.
But this is provided only on demand basis, following traffic requests.
In the below illustration, LISP router (xTR3) provides routing access to two separate VRF domains (VRF3
and VRF4) that are locally connected to the router. If a user configures a LISP Extranet policy on the MS that
allows IID 300 and IID 400 to communicate with each other, xTR3 dynamically discovers the policy and
allows host 10.3.3.3 and host 10.4.4.4 to talk to each other across VRF boundaries.
