Motivation Use Cases for IP-based tunnels: Partial deployment of MPLS-SPRING as described in [I-D.xu-spring-islands-connection-over-ip], where IP tunnels are used between MPLS-SPRING-enabled routers so as to traverse non-MPLS routers. Partial deployment of MPLS-BIER as described in Section 6.9 of [I-D.ietf-bier-architecture], where IP tunnels are used between MPLS-BIER-capable routers so as to traverse non MPLS-BIER[I-D.ietf-bier-mpls-encapsulation] routers. Remote Loop Free Alternate repair tunnels as described in [RFC7490], where tunnels are used between the Point of Local Repair and the selected PQ node. The ingress needs to select a type of tunnel which is supported by the egress. This document describes how to use OSPF Router Info LSA to advertise the tunneling capabilities of egress nodes.

Proposed Solution Routers advertises their supported encapsulation type(s) by advertising a new TLV of the OSPF RI [RFC4970], referred to as Encapsulation Capability TLV. The Value field contains one or more Encapsulation Type sub-TLVs with each indicating a particular encapsulation format (e.g., GRE). It currently defines the following encapsulation types: L2TPv3, GRE, Transmit Tunnel Endpoint, IPsec in Tunnel-mode, IP-in-IP with IPsec transport mode, MPLS-in-IP with IPsec transport mode, IP-in-IP, VXLAN, NVGRE, MPLS, MPLS-in-GRE, VXLAN-GPE, MPLS-in-UDP, MPLS-in-UDP with DTLS, MPLS-in-L2TPv3, GTP. Encapsulation Type sub-TLVs

Proposed Solution (con’t) The Value field of the Encapsulation Types sub-TLV contains zero or more Tunnel Encapsulation Attribute sub-TLVs which further describe associated attributes of a given tunnel type. It currently defines the following Tunnel Encapsulation Attribute sub-TLVs: Encapsulation Parameters: sub-TLV type code=1 has its format defined in [RFC5512] under the name Encapsulation sub-TLV. One example is the GRE key field. Encapsulated Protocol: sub-TLV type code=2 has its format defined in [RFC5512] under the name Protocol Type indicating the allowed tunnel payload types. End Point: sub-TLV type code=3 The value field carries the Network Address to be used as tunnel destination address. Color : sub-TLV type code=4 The color value is user defined and configured locally on the routers. It may be used by the service providers to define policies.

Next Steps WG adoption?
