I have a scenario where its desirable to occasionally alter the routes for a network, or group of IP addresses, on a Cat 4000.
Essentially- there will be times when their conventional WAN route will be off limits, and we will need to use an internet vpn.
But: the networks are shared by 2 or 3 locations, and altering the route in the switch will have the undesired effect of knocking out the other locations which share the network. Only one location at a time will have to use the vpn.
Is it possible to configure the Catalyst to choose a route for a packet based on its individual IP address, rather than it's network? This way, we can alter a group of IP addresses on a network and their routes and not knock out the other locations that share the particular network.
Network address 18.104.22.168 at Location A needs to go to VPN access, as its gateway needs maintenance. BUT: changing the routes in the Cat will also knock out Location B (22.214.171.124) and C (126.96.36.199) whose gateways are unaffected.
