Hi, We are combining an couple offices next week & i need some advice. The networks already have VLANs set up. we have a Cisco 3550 Layer 3 switch set up to route traffic. The servers are on this site also. The network IP's are 10.1.1.x, 10.1.4.x & 10.1.5.x. Servers reside on all of those networks. The network they are moving to is on a 10.1.3.x network. We have a Cisco PIX 506e & 515 set up to do VPN between the 10.1.1.x & 10.1.3.x networks. I have ordered another smart switch to put on the 10.1.3.x network so i can create the same VLANs on that network. (10.1.4.x & 10.1.5.x.) Am i thinking right that i need to do this, or should i be going a different route to set up the networks & route traffice the way i need to? I really want to keep the IP Scheme that everyone is already on, but if this cannot be done, i can do something else. I did read one situation from http://itknowledgeexchange.techtarget.com/itanswers/site-to-site-problems/ but this setup is almost the same as mine without the VLANs. Any assistance is greatly appreciated.
