IP Routing Commands 1059
User Guidelines
Apply an ACL rule on the VLAN interface to perform policy based routing
based on the VLAN ID as a matching criteria for incoming packets. Packets
matching a deny rule or a deny route-map are routed using the routing table.
There is no implicit deny all at the end of a route map. Packets not matching
any clause are routed using the routing table.
Route maps with no set clause are ignored.
Example
The following example creates (or edits) the route map equal-access as the
first route map in the system for allowing matching packets into the system.
Route-map mode is also entered.
console(config)#route-map equal-access permit 0
set interface null0
Use this command to drop a packet instead of reverting to normal routing for
packets that do not match the route map criteria. This command should be
configured as the last entry in the route-map as no further set clauses will
operate on a dropped packet. Use the no form of this command to remove the
set clause from a route map.
Syntax
set interface null0
no set interface null0
• null0 — Specifies the null0 interface used to drop packets.
Default Configuration
There is no default configuration for this command.
Command Mode
Route Map mode
