GRE and IP-in-IP Tunnels for Virtual Aggregation
Huawei
MPI-SWS
The document "FIB Suppression with Virtual Aggregation" [I-D.francis-intra-va] describes how FIB size may be reduced. The latest revision of that draft refers generically to tunnels, and leaves it to other documents to define the usage and signaling methods for specific tunnel types. This document provides those definitions for GRE and IP-in-IP tunnels.
