Hello all,
I have a Cisco 1841,c1841-ipbase-mz.124-20.T4.bin, with 2x HWIC-1ADSL-M.
I have managed to bond 2x DSL with PPP multlink with the config below and traffic is being sent equally across both DSL circuits. However if i disconnect either of the DSL cables connectivity fails. I was expecting connectivity to continue to work just over the one circuit.
Has anyone else come across this issue or have any ideas as to how to resolve this?
Many thanks,
