I have two sites  that are now connected through MPLS wan connection,,but I need to eliminate the MPLS WAN,, and  now  these two are now conencted  by a LAN TO LAN connection. I just received in both ends an ethernet cabling  from the vendor,, but I would like to know how can I establish the communications between these 2 sites, if they are having different subnets. I am planning to connect them through the switches (but just the switch of site B is a layer 3 switch).

Each site will need a layer 3 switch or router with static route statements used to direct traffic.

A second option that might work, depending on the setup of the Metro LAN link, would be to increase the subnet size at each site to include both sites, and then set the default gateway on all the devices at site A to the IP of the site B layer 3 switch.  This would probably work, but I wouldn't recommend it because it will but a lot of traffic on the Metro link that could be handled locally by a layer 3 switch at site A.

Correction: I incorrectly stated you would a layer 3 switch or router.  A layer 2.5 switch with ip routing enabled would also work and be cheaper then either a layer 3 switch or router.

Thanks!!, let me tell you that on site B we will implement VLANs so ,, I do know I must put trunking mode on site B port  in order to pass the vlans  to Site A, but in  site A, what can I do?

I don't have enough budget to get a Switch 2.5 layer for site A.

Please can yyou advise me?

You should be able to trunk the connections and use the ip route commands to direct the traffic.  Can you contact the Metro LAN provider and verify that the connection will preserve VLAN tagging and then verify that eh the "ip routing" command is present on both switches?

In the world of WAN, QoS is a pretty important topic for most, if not all, networks. Some WAN technologies have QoS mechanisms built in, but others, such as some L2 WAN's, don't have QoS control in the provider cloud.
