Implementing Policy-Based Routing With Ftos; Non-Contiguous Bitmasks For Pbr; Hot-Lock Pbr - Dell Force10 C150 Configuration Manual

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.

(via Gi 8/1), ARP resolved
Applied interfaces:

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.
