Hi all I want help regarding my scenario which is as follows. I have one central and tow remote sites. Both two remote sites are connected with central through Wireless Ethernet Bridge (high speed). At Central site Ethernet cable from both Wireless Bridge are connected to switch and Cisco 2620 is used for routing between 3 different VLAN ( two for remote and one for central). So at central site I have 3 sub interface on Fast Ethernet each having IP address of separate net. I also require Sync Dial Backup for each remote site. So I placed one 1601 and Sync dialup modem on each remote site and dialup modems at central connected with sync port of 2620. But I can't understand how to configure online (automatic) backup because if any of wireless link will break or down, Ethernet ports will not down and dialer will not initiate. Also for manual backup, if I manually dial to central site from any remote site then after connected to central, I have same IP net on both site of link, it means Ethernet port of 1601 and fast Ethernet port of 2620 have Ethernet IP from same net. Can anybody guide me how I run my main links on Wireless Ethernet Bridge and backup link on dialup with routers?
