● IP address of the next-hop router in the forwarding route
● IP protocol number
● Source address with mask information
● Destination address with mask information
Example: Creating a Rule
DellEMC(conf-redirect-list)#redirect ?
A.B.C.D Forwarding router's address
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ?
<0-255> An IP protocol number
icmp Internet Control Message Protocol
ip Any Internet Protocol
tcp Transmission Control Protocol
udp User Datagram Protocol
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip ?
A.B.C.D Source address
any Any source host
host A single source host
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 ?
Mask A.B.C.D or /nn Mask in dotted decimal or in slash format
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 ?
A.B.C.D Destination address
any Any destination host
host A single destination host
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 77.1.1.1 ?
Mask A.B.C.D or /nn Mask in dotted decimal or in slash format
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 77.1.1.1 /32 ?
DellEMC(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 77.1.1.1 /32
DellEMC(conf-redirect-list)#do show ip redirect-list
IP redirect-list xyz:
Defined as:
seq 5 redirect 3.3.3.3 ip host 222.1.1.1 host 77.1.1.1
Applied interfaces:
None
You can apply multiple rules to a single redirect-list. The rules are applied in ascending order, starting with the rule that has the
lowest sequence number in a redirect-list displays the correct method for applying multiple rules to one list.
Example: Creating Multiple Rules for a Redirect-List
DellEMC(conf)#ip redirect-list test
DellEMC(conf-redirect-list)#seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any
DellEMC(conf-redirect-list)#seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any
DellEMC(conf-redirect-list)#seq 20 redirect 10.1.1.3 ip 20.1.1.128/24 any
DellEMC(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 20.1.1.128/24 any
DellEMC(conf-redirect-list)#
NOTE:
Starting with the Dell EMC 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.
