AT&T ASE, Customer Cisco 3750E <=> AT&T Brocade
Posted on 2015-01-08
Asking for a friend.. He has a client who is sending traffic out to various locations at layer 2 over the AT&T ASE cloud.
The client L2 device is a Cisco 3750E which connects to two AT&T CPE (Brocade switches.) The issue is that the client wants the traffic to be load balanced over the two L2 WAN circuits. Currently all traffic goes in/out on one. My first thought was "aha - use etherchannel and LACP bada bing you're done". But evidently AT&T would allow speak about use CEF for load balancing over the two 10Gig circuits. Two questions:
-Does anyone have experience with AT&T ASE (Switched Ethernet) and can you in fact implement the connection from your gear to their configured as an etherchannel pair??
-If you in fact must use CEF load balancing - is there a design doc which would explain how to implement this coming from a Cisco environment?
Long shot - but hey. :-)
