If you want the new router to communicate with the old router on only one VLAN, then you preferably configure the switch port as an 'access' port, for that VLAN.

If you want the new router to communicate on all VLANS (for example if you want to run HSRP) then the ports on switch and new router should be configured in the same way as for the old router.

The IP to use in the new router should be in the same subnet as the IP on the old router - on the relevant VLAN. You should also make sure that IP is not included in the DHCP pool on the old router.

Hi pergr,

This is my router configuration:

Oldrouter# ip dhcp pool vlan-2
Oldrouter# network 255.255.255.0
Oldrouter# ip default 10.10.20.1
Oldrouter# interfase gig0/1.2
Oldrouter# ip add 10.10.20.1 255.255.255.0
Oldrouter# inter gig0/1
Oldrouter# no shutdown

Connected to the switch with trunk port

Now for the new router which ip should I give and what switch port mode?

Thanks

What do you want to do with the router?
What traffic do you want to route?
Do you have a topology diagram?
