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 test l2–switch
● redirect-list-name is the name of a redirect list to apply to this interface.
● FORMAT: up to 16 characters
●
You can use the l2–switch option to apply the re-direct list to Layer2 traffic.
NOTE: You can apply the l2–switch option to redirect Layer2 traffic only on a VLAN interface. This VLAN interface
must be configured with an IP address for ARP resolution. The Layer2 PBR option matches the layer2 traffic flow. If you
un-configure this option, then the Layer2 traffic is not matched.The Layer3 routing is not affected on the same interface
on which Layer2 PBR is applied. The port from which Layer2 packets egress and the destination MAC are re-written from
static ARP. Layer 2 packets with the re-written destination MAC are forwarded through the outgoing port on the same
incoming VLAN interface. The l2-switch option ensures that the outgoing VLAN and MAC-SA are changed and TTL is
not decremented.
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 1/1 interface.

DellEMC(conf-if-te-1/1)#ip redirect-group xyz
