Hello All,
I was creating a simple topology, in which i am creating a router on stick design, for l2 vlan to communicate with other vlans on the same l2 switch.
I have 3 subinterfaces on the router end, and consequently 3 vlans on the switch end. Port connecting to router from switch is in trunk. One of the vlans on the switch (vlan 101) has been made a management vlan, by creating an interface for the same and assigning an ip on it.
Now since the default gateway on the switch end , should be of the same subnet as the SVI, i configured same subnet ip address on one of the subinterface of router, which are connected to the trunk port of the switch
i have configured both line vty 0 4 and generated rsa keys on both switch and router. And i am able to ping every interface and ip from both switch and router. but i still am not able to ssh into router from switch. It asks for password, but does not log you in. And it is not a password fault (it was a very simple one).
Do we need to explicitly define management interface or something like that. Also if i am not wrong, we can ssh into subinterfaces, right?
