To enable a PBR, you create a Redirect List. Redirect lists are defined by rules, or routing policies. The
following parameters can be defined in the routing policies or rules:
•
IP address of the forwarding router (next-hop IP address)
•
Protocol as defined in the header
•
Source IP address and mask
•
Destination IP address and mask
•
Source port
•
Destination port
•
TCP Flags
Once a redirect-list is applied to an interface, all traffic passing through it is subjected to the rules defined
in the redirect-list.
The traffic is forwarded based on the following:
•
Next-hop addresses are verified. If the specified next hop is reachable, then the traffic is forwarded to
the specified next-hop.
•
If the specified next-hops are not reachable, then the normal routing table is used to forward the
traffic.
•
Dell Networking OS supports multiple next-hop entries in the redirect lists.
•
Redirect-Lists are applied at Ingress.
