Hi all;
I'm jack of all trades, master of none for my organization so this is a basic question. I've been out to cisco.com and other multitudes of sites but the examples appear to be way more complex than what I'm trying to do so I don't know what's necessary and what's not. Any pointers would be appreciated.
We have three sites all connected by 3rd-party fiber. Previously, we had vendor supplied Cisco 3400 ME switches at each site that plugged into our 1841 routers that were connected to our Linksys switches. I just finished ripping out the switches and replacing them with 3750G PS switches at each site. Now I want to pull the 1841 routers at the two remote sites and use the 3750s to route since I can get a fiber hand off from the 3400s from the vendor. (I'm not worried about outside connectivity at this time since that's a whole 'nother can of worms.)
At one of my sites, we have an addressing scheme of 10.28.20.0/24 with a default gateway of 10.28.20.1. The new 3750 has the default VLAN1 as 10.28.20.2. The 1841 has a LAN address of 10.28.20.1 and a WAN address of 10.28.254.2/24 with a route back to 10.28.254.1. The F/E WAN connection plugs into the 3400 ME switch that then runs back to the data center. The data center router has two VLANs with this site as VLAN3 10.28.254.1/24.
Sooo...my question is how I apply the 10.28.20.1 and 10.28.254.2 addresses to the 3750. Do I readdress the switch as 10.28.20.1 and apply the 10.28.254.2 address to the G/E52 physical port? Or do I create a second VLAN with the 254 address? Or what?? Like I said, basic to you guys but slightly puzzling to me in the timeframe I have to make this work.
Thanks for any help in advance. Let me know if you want the configs.
