We have recently been purchased by another company. They need to connect to our hq from two of their remote sites. They will be dropping two lines from two different providers to our hq. One line is a 100mb line that will be optical (fiber), the other is also a 100 mb line that will be electrical (rj45). In our hq we have two 6509's, one is on our ground level and the other is on the 2nd floor. How can we acheieve redunancy for the new lines that will be run to our new owners?
(We also have 2960 switches that provide redunancy to our other site by connecting the fiber uplink from that site in the 2960 and both 6509s.)
