Connecting Multiple Networks

Hello,

Thank you

I believe the "less painful" method of integrating multiple subnets to your main subnet is MPLS.

One of the major benefits of MPLS is that each VRF can share the same IP Address and they are still classified as "separate".

This question is a little broad and tough to answer without a better idea of how traffic flow thru your network,,,,,,but for a very basic, not so secure soultion...

Guessing the 3700 are acting as the the core?

Connect new switches back to core using etherchannels

Adjust to STP priority on new switches to maintain root

Add/Edit/Prune vlans on new switches.

If those 3560 came from outside your current I double check that they are NOT running VTP.

I'm sorry for not giving mor information.

The networks we are adding to the Datacenter all have VTP running on them in a different domain, will this cause a problem, and can we keep them seperate - like one is CSI and the others are PCSI /SCCUL/ League.

They have twenty or more Vlan's on the switches we are adding and the good thing they are for the most part on the same networks except for two or thee.

I hope this helps

Thanks

Cisco have any documentation on doing this
