Moving datacenters - transparent bridging programming help needed on Cisco ios

I need to move a datacenter but it will be a slow process.  In the beginning there will be a few systems in the new datacenter and the only traffic needed from DC to DC would be management.  There will be a new internet circuit in the new DC to handle those other items.  So, if the old DC is 192.168.1.x then I'd like to keep the new DC at 192.168.1.x so that I can move equipment and not worry about re-iping things or their dependencies.  the thought by someone is to set up a data T1 between the two sites and do transparent bridging.

Can someone give me the ios configuration for this?  and please don't just send me a link to some Cisco article that I"m not going to understand and is going to be missing half the pieces.   You help is MUCH appreciated

A T1 would be incredibly slow to carry internet traffic, much less datacenter traffic.  Get a fiber connection between the two, or a very fat internet connection.

Layer 2 tunnel is what you're looking for.  Using routers, not switches.  It creates a Layer 2 bridge over a Layer 3 connection.  This will let you have the same subnet on both sides of the connection.  L2TP.

Cisco routers might be pricy unless you get them second-hand.  I'm pretty sure Sonicwall TZ series can do it.

Couple those to an 100+Mbps internet connection and you'll be set.

I'd avoid the SOHO IP ranges of 192.168.x.y...to much routing conflict when you're making VPN connections.  Use the other private ranges in 10.x.y.z or 172.[16-31].y.z.

...couple those to an _existing_ internet connection...

You shouldn't have to buy a new circuit.  But you can't do it over a cheap asymmetric connection like residential-class DSL, cable, FIOS, or Uverse.  Your weakest link is the slowest speed.

So, 30/5 is really a 5Mbps link or less.  Some carriers will no longer sell symmetric like 35/35 or 50/50 FIOS.  You'll have to get the biggest pipe you can afford to get the best upstream speed.  And, pay for the STATIC IP address.  Should be free or $5/month.

FIOS has a 300Mbps package with 30-50 upstream for around $300/month with static IP.

The question was really what ios commands on the Cisco router were needed to do tunneling or a bridge.  I didn't really get that, hence the C.  But thanks for the advice

Something like this?  Not sure the minimum level of router you'd need.  This sample is from an 2811 only working as the Layer2 bridge.  The LAN/WAN routing is handled by a separate firewall/router.
