The traffic is forwarded based on the following: 1. Next-hop addresses are verified. If the specified next hop is reachable, then the traffic is forwarded to the specified next-hop. 2. If the specified next-hops are not reachable, then the normal routing table is used to forward the traffic. 3. FTOS supports multiple next-hop entries in the redirect lists. 4. Redirect-Lists are applied at Ingress. Implementing Policy-based Routing with FTOS Non-contiguous bitmasks for PBR Non-contiguous bitmasks for PBR allows more granular and flexible control over routing policies. Network addresses that are in the middle of a subnet can be included or excluded. Specific bitmasks can be entered using the dotted decimal format. FTOS#show ip redirect-list IP redirect-list rcl0: Defined as: seq 5 permit ip 200.200.200.200 200.200.200.200 199.199.199.199 199.199.199.199 seq 10 redirect 1.1.1.2 tcp 234.224.234.234 255.234.234.234 222.222.222.222/24 eq 40 ack, Next-hop reachable (via Gi 8/1), ARP resolved Applied interfaces: Gi 8/0 Hot-Lock PBR Ingress and egress Hot Lock PBR allow you to add or delete new rules into an existing policy (already written into CAM) without disruption to traffic flow. Existing entries in CAM are adjusted to accommodate the new entries. Hot Lock PBR is enabled by default. Configuration Task List for Policy-based Routing To enable the PBR: 1.Create a Redirect List 2.Create a Rule for a Redirect-list 3.Apply a Redirect-list to an Interface using a Redirect-group Policy-based Routing | 753
