I currently have two seprate switches connected via separate Fas interfaces to the same router. I am planning to replace the current router with a new 3800 router and use the same Gig interface to connecet both separate switches (segments) by creating interVLANs. The current production router is configured as follows:
Fas 0/1 IP: 10.10.51.1
SW1: VLAN 1: 10.10.51.2
Default Gateway: 10.10.51.1
Fas 3/0 IP: 10.17.54.1
SW1: VLAN 1: 10.10.54.2
SW2: VLAN 1: 10.10.54.3
SW1: VLAN 1: 10.10.54.4
SW1: VLAN 1: 10.10.54.5
Default Gateway: 10.17.54.1
So, my plan is to configure the new router with one of the Gig interfaces with the following:
Gig 0/1.51
'dot1q encapsulation
IP address: 10.10.51.1
Gig 0/1.54
'dot1q encapsulation
IP address: 10.10.54.1
SW1: VLAN 1: 10.10.51.2
'dot1q encapsulation
Defafult Gateway:?
SW2: VLAN 1: 10.10.54.2
Default Gateway: ?

My questions are:
1- Do I need to create a native VLAN on the router? If so, what should the default gateway ip addresses to be assigned to the switches?
Thanks,
