The redirect rule supports Non-contiguous bitmasks for PBR in the Destination router IP address
The following example shows how to create a rule for a redirect list by configuring:
• 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
Dell(conf-redirect-list)#redirect ?
A.B.C.D Forwarding router's address
Dell(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
Dell(conf-redirect-list)#redirect 3.3.3.3 ip ?
A.B.C.D Source address
any Any source host
host A single source host
Dell(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
Dell(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
Dell(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
Dell(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 77.1.1.1 /32 ?
Dell(conf-redirect-list)#redirect 3.3.3.3 ip 222.1.1.1 /32 77.1.1.1 /32
Dell(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
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.
