From a64448baa6150a7431d55e0e65d0b51d62c4b5be Mon Sep 17 00:00:00 2001 From: Don Slice Date: Thu, 2 Feb 2017 12:58:33 -0500 Subject: zebra: labeled unicast handling Support install of labeled-unicast routes by a client. This would be BGP, in order to install routes corresponding to AFI/SAFI 1/4 (IPv4) or 2/4 (IPv6). Convert labeled-unicast routes into label forwarding entries (i.e., transit LSPs) when there is a static label binding.
