[x] switch - ethernet etherchannel / no spanning tree
(x) router - ethernet etherchannel
Each connection from both routers is a 4 port etherchannel. Is it possible to merge the etherchannels to make it look like 1 connection to the routers.
I am not sure this is possible and from a design perspective due to the fact that if the etherchannel betweek s2 and s3 has 3 of the 4 ports fail both routers still pass 400MBs of traffic down that path.
does spanning tree normally adjust the cost of the etherchannel link when ports fail?
Can routing protocols gather information from layer 2 to be aware of the link status change?
