I was wondering if anyone had any insight on the following:
We have a hub and spoke network using Metro Ethernet and routing is performed by 3750G core switches at each site using EIGRP. Distributions switches are a mixture of 3550 and 3560.
We have a couple of sites that are really close to each other and I actually have a fiber link between the 2 sites that I can connect as a backup link in case one of the Metro Ethernet links go down. The fiber link is terminated in closets that have only 3550 switches.
My question is, can I connect the 2 separate networks with the fiber using the gigabit ports on the 3550 switches or do I need to extend the fiber to the core since it is doing the routing?
Also if I use the 3550's would I need to make the gigabit ports trunking ports or create a vlan and make it an access port?
Thanks for your help.
