            Advertising Encapsulation Capability Using IS-IS
                   draft-xu-isis-encapsulation-cap-00

Abstract

   In a particular network environment where MPLS-SPRING-enabled routers
   are partially deployed, it needs to transport MPLS traffic through an
   IP-based tunnel between two MPLS-SPRING-enabled routers so as to
   traverse non-MPLS routers.  The ingress of the IP-based tunnel must
   know which encapsulation type is supported by the egress of that IP-
   based tunnel.This document describes how to advertise the
   encapsulation capability of MPLS-SPRING-enabled routers using IS-IS.

1.  Introduction

   [I-D.xu-spring-islands-connection-over-ip] describes a particular
   network environment where MPLS-SPRING-enabled routers are partially
   deployed and therefore it needs to transport MPLS traffic through an
   IP-based tunnel between two MPLS-SPRING-enabled routers so as to
   traverse non-MPLS routers.  The ingress of the IP-based tunnel (i.e.,
   tunnel encapsulator) must know which encapsulation type is supported
   by the egress of the IP-based tunnel (i.e., tunnel decapsulator).This
   document describes how to advertise the encapsulation capability of
   MPLS-SPRING-enabled routers using IS-IS.

1.1.  Requirements Language
