For information on how to configure policy-based routing, see the section
in this chapter.
Equal Access
The following example provides two sources with equal access to two different service providers.
Packets arriving on interface fastethernet 3/1 from the source 1.1.1.1 are sent to the switch at 6.6.6.6 if
the switch has no explicit route for the destination of the packet. Packets arriving from the source 2.2.2.2
are sent to the switch at 7.7.7.7 if the switch has no explicit route for the destination of the packet. All
other packets for which the switch has no explicit route to the destination are discarded.
Switch (config)#
access-list 1 permit ip 1.1.1.1
access-list 2 permit ip 2.2.2.2
!
interface fastethernet 3/1
ip policy route-map equal-access
!
route-map equal-access permit 10
match ip address 1
set ip default next-hop 6.6.6.6
route-map equal-access permit 20
match ip address 2
set ip default next-hop 7.7.7.7
route-map equal-access permit 30
set default interface null0
Note
If the packets you want to drop do not match either of the first two route-map clauses, then change |
set default interface null0
to
set interface null0
.
