What really Orcon have de-prioritised IMCP.... wow that's going to cause issues with troubleshooting and potentially other issues.
I wonder if this is a DDOS protection.....
Only de-prioritesed when the ICMP is targeted at the routers control plane (like a traceroute for example).
This is comon-practise, as we want the routers to be handling bgp requests etc before replying to ICMP traffic.
Our BNG is bit harsh I agree. Its on the todo list to look at.
