From 69a47bd63d00230a6eb80da1e6358865e2f62a9a Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Tue, 21 Nov 2017 13:08:44 +0100 Subject: HC2VPP-259: add support for mpls lookup Translates pop-and-lookup operation of /hc2vpp-ietf-routing:routing/hc2vpp-ietf-mpl:mpls/ hc2vpp-ietf-mpls-static:static-lsps/static-lsp to mpls_route_add_del call. Configuring mpls lookup-type, as defined in vpp-mpls yang module, is required. Other lookup types (ipv4/ipv6) are not supported yet.
