Raw Blame History

From 409f98ab443682ec360e3e76954f1c8985b3371d Mon Sep 17 00:00:00 2001
From: Igor Ryzhov <iryzhov@nfware.com>
Date: Thu, 28 Jan 2021 02:41:07 +0300
Subject: [PATCH 1/2] ospfd: don't rely on instance existence in vty
Store instance index at startup and use it when processing vty commands.
The instance itself may be created and deleted by the user in runtime
using `[no] router ospf X` command.
Fixes #7908
Signed-off-by: Igor Ryzhov <iryzhov@nfware.com>
