I'm trying to do that in cisco paket racer
in switch i have vlan 10 and vlan 20 and in the router port0/0 i used no ip add then i used encapsulation dot1q to share the port with this tow vlan i have.
i did the SSH in the router and in the switch in vlan1 but now i can go in into the router with a pc who is connected to vlan 10 or 20 but i can't connect the switch
have anyone an answer for why i can't connect the switch with SSH

because the switch has a different IP address and belongs to VLAN 1
On Router, try add below config
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 10.0.0.1 255.255.255.0
no shutdown
On SWITCH :
ip default-gateway 10.0.0.1
Try Ping from router to 10.0.0.15 - Ping ok ?
Try ping from switch to 10.0.0.1 - Ping ok ?
Add RSA Keys for SSH :
######### Generate SSH keys :
ip domain-name bb.com (change what ever you like)
crypto key generate rsa ( use 1024 or higher for security)
Then test from Device to connect to switch.

From Vlan 10 and 20 are you able to ping Router IP ?
can you post switch side and router relevant config to look ?
