From 8079a4138d61500117ebbffb250ceba0a894f9c0 Mon Sep 17 00:00:00 2001 From: Philippe Guibert Date: Wed, 2 Nov 2022 18:17:21 +0100 Subject: lib, bgp: add initial support for asdot format AS number can be defined as an unsigned long number, or two uint16 values separated by a period (.). The possible valus are: - usual 32 bit values : [1;2^32 -1] - <1.65535>.<0.65535> for dot notation - <0.65535>.<0.65535> for dot+ notation. The 0.0 value is forbidden when configuring BGP instances or peer configurations. A new ASN type is added for parsing in the vty. The following commands use that new identifier: - router bgp .. - bgp confederation .. - neighbor <> remote-as <> - neighbor <> local-as <> - clear ip bgp <> - route-map / set as-path <> An asn library is available in lib/ and provides some services: - convert an as string into an as number. - parse an as path list string and extract a number. - convert an as number into a string. Also, the bgp tests forge an as_zero_path, and to do that, an API to relax the possibility to have a 0 as value is specifically called from the tests.
