However, this is not recommended Most devices can't handle 2 default gateways well, and if they do, they won't work in the way that is useful. The device uses the matched route with the highest subnet mask, that is, the longest prefix Defining more than one equal cost default route entry causes the traffic sent to the default route to be distributed among the specified gateways. ICMP rate limiting. The default configuration routes the local network through Although multiple virtual device groups can be configured for the same set of devices, the hosts must be configured for different default gateways, which results in an extra administrative This example shows how to configure two default gateways on a Catalyst 4000 family, Catalyst 2948G, or Catalyst 2980G switch, with one default gateway reachable through the sc0 Multiple Default Gateways: You can set multiple default gateways on a Cisco switch by using the ip default-gateway command multiple times. I would suggest reviewing the Load Balancing ISE Web You can have as many gateways as you want in one Vlan, but you can only have 1 default per host.
