I'm a little confuse and I don't know how it can be possible to do something with 2 distant sites linked with one NIC at each side.
My first react was that I need to have 2 Nic and for best availability 2 link but my client have only one.
So at each side it have already 2 switch 4506 with HSRP configured so they only need to change the WAN cable from one switch to the nother.
Somebody have an idea, what is the best thing I can do.
Thanks a lot
