Hi Lutha,

on EXOS, you can write an ACL (.pol file) that matches on the traffic and then redirects it to a different next-hop. That ACL combines the functionality of both the route-map and the ACL you used on Cisco IOS. That ACL can then be bound to e.g. a VLAN.

You might want to take a look at the chapter Routing Policies in the EXOS User Guide.

Thanks,
Erik
