We have a combination of policy based routing and IP helper (DHCP relay) configured on a router interface. Since client DHCP stations use all 0's broadcast, there is an impact, depending on what order the router processes the mentioned 2 sevices.
#1 If PBR is 1st, then the broadcast if not satisfied by the PBR ACL will eventually hit default routing and get dropped because it never hits the ip helper.
#2 If IP HELPER is processed 1st then broadcasts should work as hoped
Can anybody confirm ?
