I need to purchase a new internet switch (8 public IP addresses). I'm a bit confused as to multi-homing the router.
Currently I have 1 public IP on one interface on the VPN router (Cisco 2691) which connects to the internet switch and one internal IP on my LAN side.
The idea is that if the internet switch goes down, the VPN traffic could be carried over the other network interface to the new switch. There is only one ISP, so routing to a separate network isn't possible here.
Any help would be appreciated.
