In a single AS network that provides both L2VPN and L3VPN services, how should routers be managed by administrators and operators? Should they access the routers loopback interfaces via pure L3 routing to establish SSH connections, or should a separate dedicated VRF be allocated so that they connect to the loopback through an L3VPN?

I have a router that uses a SIM card for connectivity, and I create a socket connection. After the connection is disrupted, when I attempt to send a packet from the server using the previously established socket, the router responds with a RST (reset) packet. I have checked the firewall of the router but it seems to be deactivated.
