I have created a network in Cisco DevNet - Cisco Modeling Enterprise lab.
The routers are connected to an unmanaged switch, the switch is connected to the external connector. External connector is set to bridged.
I have set a correct IP address for these interfaces in the routers (10.10.20.0/24, eg: 10.10.20.101/24), enabled SSH and everything, but the connection is really unreliable.
I have tried to put these interfaces into a VRF and add a route for that VRF - like in the sample config - that's even worse. Even the original Sample Network is really unreliable.
Sometimes SSH works, sometimes not (Connection timed out). Sometimes it drops when I have already SSHd into the router. Then I cannot access it again... Sometimes it appears again.
Alpine Linux hosts are working always correctly.
I don't know I'm doing wrong. Can someeone give me a hint?
