/**

* Tunnel Endpoint Information Base.
|
|
*
|
|
* A TEIB entry represents the mapping between a peer on an interface in the overlay
|
|
* and a next-hop address in the underlay.
|
|
* i.e. there's a multipoint tunnel providing the overlay (henace a peer on
|
|
* that tunnel) which is reachable via 'tunnel destination' address in the
|
|
* underlay.
|
|
*
|
|
* Such overlay to underlay mappings might be providied by a protocol like NHRP
