We have a Cisco 3640 router with two T1 interface and configured for BGP between two service providers and we have a cisco pix firewall behind the cisco router. Is there any automatic failover options available incase my cisco 3640 router crashes? Can i have one more cisco 3640 router with same configuration loaded as standy and make it active once the primary router crashes? Is there any equipment that can be placed in between the ISP Jack and the router which splits the connection to both the router and starts sending pockets to the standby router once the active router goes down like a Y cable?
Thanks in Advance
