Example: Creating Multiple Rules for a Redirect-List
Dell(conf)#ip redirect-list test
Dell(conf-redirect-list)#seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any
Dell(conf-redirect-list)#seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any
Dell(conf-redirect-list)#seq 20 redirect 10.1.1.3 ip 20.1.1.128/24 any
Dell(conf-redirect-list)#show config
!
ip redirect-list test
seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any
seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any
seq 20 redirect 10.1.1.3 ip 20.1.1.0/24 any
Dell(conf-redirect-list)#
NOTE: Starting with the Dell Networking OS version 9.4(0.0), the use of multiple recursive routes with the same
source-address and destination-address combination in a redirect policy on an router.
A recursive route is a route for which the immediate next-hop address is learned dynamically through a routing protocol and
acquired through a route lookup in the routing table. You can configure multiple recursive routes in a redirect list by entering
multiple
seq redirect
commands with the same source and destination address and specify a different next-hop IP address.
In this way, the recursive routes are used as different forwarding routes for dynamic failover. If the primary path goes down and
the recursive route is removed from the routing table, the
seq redirect
command is ignored and the next command in the
list with a different route is used.
Apply a Redirect-list to an Interface using a Redirect-group
IP redirect lists are supported on physical interfaces as well as virtual local area network (VLAN) and port-channel interfaces.
NOTE: When you apply a redirect-list on a port-channel, when traffic is redirected to the next hop and the destination
port-channel is shut down, the traffic is dropped. However, the traffic redirected to the destination port-channel is
sometimes switched.
To apply a redirect list to an interface, use the following command. You can apply multiple redirect-lists can be applied to a redirect-
group. It is also possible to create two or more redirect-groups on one interface for backup purposes.
Apply a redirect list (policy-based routing) to an interface.
INTERFACE mode
ip redirect-group redirect-list-name
•
redirect-list-name
is the name of a redirect list to apply to this interface.
• FORMAT: up to 16 characters
To delete the redirect list from this interface, use the
no ip redirect-group
command.
In this example, the list
xyz
is applied to the tenGigabitEthernet 2/1 interface.
Example: Applying a Redirect-list to an Interface
Dell(conf-if-te-2/1)#ip redirect-group xyz
Dell(conf-if-te-2/1)#
Example: Applying a Redirect-list to an Interface
Dell(conf-if-te-1/1)#ip redirect-group test
Dell(conf-if-te-1/1)#ip redirect-group xyz
Dell(conf-if-te-1/1)#show config
!
