How to configure default routing so different default routes are used based on the source of the packet, such as based on which devices or users are originating the packets.
The default route is already configured on the router, and you want to policy route certain users to different Internet Service Providers (ISPs).
Issue the set ip default next-hop command in the route-map command configuration mode.
Configure Policy Based Routing (PBR) specifying a different default IP next hop for interested traffic by issuing a route-map command.
This is a sample configuration for the traffic sourced from 10.1.1.0/24, coming in on interface Ethernet0, policy routed to next-hop x.x.x.x:
int Ethernet0
ip address 10.1.1.1 255.255.255.0
ip policy-map new-gatewayroute-map new-gateway permit 10
match ip address 10
set ip default next-hop x.x.x.xaccess-list 10 permit 10.1.1.0 0.0.0.255
Note: The traffic that does not match the policy uses the default route configured in the router.
