When add node at matrix page, there comes error “The default gateway is not available”
Open the remote console of the ADWAN node OS ,execute command”ifconfig”, it turns out there is ip configuration for Nic.
Ping this Nic’s gateway, Unreachable.

Retry add host, success!
Campus new version check the host gateway, so make sure the campus host can reach it’s gateway, especially when we do the lab, it can be usually be ignored if just layer 2 forwarding.
