PBR Exceptions (Permit)
To create an exception to a redirect list, use thepermit command. Exceptions are used when a forwarding decision should be
based on the routing table rather than a routing policy.
The Dell EMC 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.
Never apply the permit statement because the redirect list covers all source and destination IP addresses.
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 the permit permit statement or PBR exception is effective, use a lower sequence number, as shown:
ip redirect-list rcl0
seq 10 permit ip host 3.3.3.3 any
seq 15 redirect 2.2.2.2 ip any any
Create a Redirect List
To create a redirect list, use the following commands.
Create a redirect list by entering the list name.
CONFIGURATION mode
ip redirect-list redirect-list-name
redirect-list-name: 16 characters.
To delete the redirect list, use the no ip redirect-list command.
The following example creates a redirect list by the name of xyz.
DellEMC(conf)#ip redirect-list ?
WORD Redirect-list name (max 16 chars)
DellEMC(conf)#ip redirect-list xyz
Create a Rule for a Redirect-list
To set the rules for the redirect list, use the following command. You can enter the command multiple times and create a
sequence of redirect rules. Use the seq nn redirect version of the command to organize your rules.
Configure a rule for the redirect list.
CONF-REDIRECT-LIST mode
seq {number} redirect {ip-address | tunnel tunnel-id} [track <obj-id>}{ip-protocol-number |
protocol-type [bit]} {source mask | any | host ip-address}{destination mask | any | host
ip-address}
● number is the number in sequence to initiate this rule
● ip-address is the Forwarding router’s address
● tunnel is used to configure the tunnel settings
● tunnel-id is used to redirect the traffic
● track <obj-id> is used to track the object-id
● track is to enable the tracking
● FORMAT: A.B.C.D
● FORMAT: slot/port
● ip-protocol-number or protocol-type is the type of protocol to be redirected
● FORMAT: 0-255 for IP protocol number, or enter protocol type
