I was wondering about Best Practice that we can protect network management traffic when there is severe congestion in backbone netework.
as you know, when backbone network has severe congestion, we can't access routers.
So, I'd like to protect important traffic such as telnet(or ssh) to router, routing protocol BGP, LDP (over TCP)
How should I configure to do it?
Actually, I have a lot of routers and interfaces. So, I can't apply specific QoS Config to routers.
as you know, I should change Routers' IP address in Qos Config ,depending on Routers' IP
I need common QoS template on all routers in a lump.
QoS template doesn't have hard coded IP address (such as, router Loopback IP)
In conclusion, I'd like to protect network management traffic(above protocols) to Router Loopback IP.
Thanks in advance.
