Configuring JUNOSe Secondary Input Policy Conditions
For JUNOSe policies, you can apply secondary
input policies to the input (ingress) side of the router interface.
Secondary input policies evaluate conditions after a route lookup.
Use the following configuration statements to configure
match conditions for JUNOSe secondary input policies:
- policies group name list name rule name traffic-condition name traffic-match-condition
{
- source-class source-class ;
- destination-class destination-class ;
- traffic-class traffic-class;
- color color;
- user-packet-class user-packet-class;
- destination-local-interface destination-local-interface ;
- }
To add conditions for JUNOSe secondary
input policies to a classify-traffic condition:
- From configuration mode, create a classify-traffic condition
inside a policy rule that has already been created and configured
for a policy list whose type is junose-ipv4 or junose-ipv6 and applicability
is secondary-input. For example, to create a traffic-condition called
rtcl within policy rule clacl:
- user@host# edit policies group junose list
ipv4 rule clacl traffic-condition rtcl traffic-match-condition
- (Optional) Configure the condition to match packets based
on the source route class.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set source-class source-class
- (Optional) Configure the condition to match packets based
on the destination route class.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set destination-class destination-class
- (Optional) Configure the condition to match packets based
on the traffic class.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set traffic-class traffic-class
- (Optional) Configure the condition to match packets based
on the packet color.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set color color
- (Optional) Configure the condition to match packets based
on the user packet class action number.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set user-packet-class user-packet-class
- (Optional) Configure the condition to match packets based
on packets destined for a local interface.
- [edit policies group junose list ipv4 rule clacl traffic-condition
rtcl traffic-match-condition]
- user@host# set destination-local-interface destination-local-interface
- (Optional) Verify the secondary input policy configuration.
[edit policies group junose list ipv4 rule clacl traffic-condition rtcl traffic-match-condition]
user@host# show
