From 188823b0809f54158b9565d8284279c0ac12683d Mon Sep 17 00:00:00 2001 From: Emanuele Di Pascale Date: Fri, 18 Jan 2019 12:39:28 +0100 Subject: [PATCH] ospfd: fix no virtual-link cmd the command was not checking correctly in all cases whether the virtual link existed. This caused bugs in some corner cases, e.g. when two virtual links were created, one of them was deleted, and the second one was reset with no authentication - this would instead create a new virtual link with the area in decimal format.
