Abstract
Networks use tunnels for a variety of reasons. A large variety of
tunnel types are defined and the ingress needs to select a type of
tunnel which is supported by the egress and itself. This document
defines how to advertise egress tunnel capabilities in OSPF Router
Information Link State Advertisement (LSAs).
