Qppb - Alcatel-Lucent 7710 SR OS Configuration Manual

QPPB

There are two main aspects of the QPPB feature:
•
•
Associating an FC and Priority with a Route
This feature uses a command in the route-policy hierarchy to set the forwarding class and
optionally the priority associated with routes accepted by a route-policy entry. The command has
the following structure:
fc fc-name [priority {low | high}]
The use of this command is illustrated by the following example:
config>router>policy-options
begin
community gold members 300:100
policy-statement qppb_policy
exit
commit
The fc command is supported with all existing from and to match conditions in a route policy entry
and with any action other than reject, it is supported with next-entry, next-policy and accept
actions. If a next-entry or next-policy action results in multiple matching entries then the last entry
with a QPPB action determines the forwarding class and priority.
A route policy that includes the fc command in one or more entries can be used in any import or
export policy but the fc command has no effect except in the following types of policies:
•
