I have two firewall's directly connected to the L3 switch & L3 switch have the default route pointed towards one of the firewall & my LAN user's have default gateway as L3 Switch. I woluld like to route some LAN IP's to other firewall. I have configured the route-map in the L3 switch & set the next hop for those IP's to other firewall inside interface, but it's not working. can any help me whether it is possible through route map or not
Why are you using a route-map? Route-maps are generally used if you need conditional routing, for example, if you need to set a particular next-hop behavior for traffic matching certain criteria, and deviating from the default routing table. If this is your only goal, you can use VRFs to separate your traffic instead of route-maps, if your platform supports it.
If you have an L3 switch, you have probably activated IP routing on the switch, with the command "ip routing", and added the default route to the existing firewall, with the "ip route 0.0.0.0 0.0.0.0
