From 03ce46219cd0fabfd4918822c5b9fed9ef880de8 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Mon, 3 Feb 2020 10:55:09 +0000 Subject: teib: Rename NHRP to TEIB Type: refactor The Tunnel Endpoint Informatiob Base (TEIB) is a better description of what it is (a mapping between tunnel endpoint address, in the overlay, and next-hop address, in the underlay) whereas NHRP is one instanc eof a control protocol that might add such endpoints.
