I have two buildings less than 5000ft from each other. I'd like to get as much bandwidth between them as possible. Wireless is not an option but I can have as many "dry-pairs" between the buildings as I'd like. I'm looking at LRE but I'd like to be able to bond several 15Mb links, there doesn't appear to be an etherchannel equivalent for LRE because the connection is really from switch to CPE. Is there one? Am I looking at the wrong technology? Any help, greatly appreciated!
