You can enter 0 for the minimum length if you simply want to ensure that the
packet does not exceed a specific size. For example, if you knew that packets
for interactive traffic in your network were generally smaller than 200 bytes,
you could enter this command to select interactive traffic:
ProCurve(config-route-map)# match length 0 200

Setting the Routing Policy in a Route Map Entry

For each route map entry used for PBR, you must also enter at least one set
command. This command specifies how selected traffic will be routed. You
can configure the router to forward these packets:
1. to an adjacent neighbor
2. through a specific interface
3. to an adjacent neighbor only if the routing table does not include an
explicit entry for the packet's destination
4. through a specific interface only if the routing table does not include an
explicit entry for the packet's destination
Use the commands shown in Table 15-19 to configure the policy.
Table 15-19. Configuring a Routing Policy in a Route Map Entry
Route Selected Traffic
to an adjacent neighbor
through an interface
to an adjacent neighbor only if a route
does not exist for the packet's destination
through an interface only if a route does
not exist for the packet's destination
When a router uses typical routing, it can learn more than one route to a
destination, which means that it can immediately begin using a backup route
if a connection fails. You can also configure backup routes for PBR. Simply
specify more than one set command or more than one next hop address or
forwarding interface in a single set command.
Command Syntax
set ip next-hop <A.B.C.D> [<secondary A.B.C.D>]
set interface <interface ID> [<secondary
interface ID>]
set ip default next-hop <A.B.C.D> [<secondary
A.B.C.D>]
set default interface <interface ID> [<secondary
interface ID>]
