Hot-Lock PBR
Ingress and egress Hot Lock PBR allows you to add or delete new rules into an existing policy (already
written into content address memory [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:
•

Create a Redirect List

• Create a Rule for a Redirect-list
• Create a Track-id list. For complete tracking information, refer to
• Apply a Redirect-list to an Interface using a Redirect-group

PBR Exceptions (Permit)

Use the command permit to create an exception to a redirect list. Exceptions are used when a
forwarding decision should be based on the routing table rather than a routing policy.
Dell Networking OS assigns the first available sequence number to a rule configured without a sequence
number and inserts the rule into the PBR CAM region next to the existing entries. Because the order of
rules is important, ensure that you configure any necessary sequence numbers.
The permit statement is never applied because the redirect list covers all source and destination IP
addresses.
Ineffective PBR Exception due to Low Sequence Number.
ip redirect-list rcl0
seq 5 redirect 2.2.2.2 ip any any
seq 10 permit ip host 3.3.3.3 any
To ensure that the permit permit statement or PBR exception is effective, use a lower sequence number,
as shown below:
ip redirect-list rcl0
seq 10 permit ip host 3.3.3.3 any
seq 15 redirect 2.2.2.2 ip any any
