I am setting up a pair of 5512-X outside network with 2x Cisco 2960C switches connecting to our service provider through an access port on each of the switch.
Since Etherchannel accross the 2960C's is not an option, would you:
1) Etherchannel from Firewall A to 2960C A and Etherchannel from Firewall B to 2960C B (with trunk between the 2960C's)
2) Each firewall have uplink to each 2960C and use redundant interfaces
Please let me know why you would favor any of the options.
