hi friends I have cisco 2600 series router with 2 port sync / async card. one port is connected internet through 64 KBPS leased line. I want to use my second port as async port so that my router will dial up to internet through second port whenever my leased line is down. will that second interface act as back up? if so, what are the commands. your help in this regard is highly apprecaited. tanx in advance bye ravee ____________________________________________________________________ Get free email and a permanent address at http://www.netaddress.com/?N=1 _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
