• Create a Track-id list. For complete tracking information, refer to Object Tracking chapter.
• 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
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
.
Dell(conf)#ip redirect-list ?
WORD Redirect-list name (max 16 chars)
Dell(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
