Navigate to the top of the configuration hierarchy in either the J-Web or CLI
configuration editor.
Perform the configuration tasks described in Table 146.
If you are finished configuring the policy, commit the configuration.
Go on to one of the following procedures:
To advertise additional routes, see "Injecting OSPF Routes into the BGP
Routing Table" on page 380.
To create a forwarding class, see "Grouping Source and Destination
Prefixes in a Forwarding Class" on page 382.
To make a route less preferable to BGP, see "Configuring Policy to Prepend
the AS Path" on page 383.
To suppress route information, see "Configuring Damping Parameters"
on page 385.

Match If ...
The route shares the same most-significant bits (described by
prefix-length ), and prefix-length is equal to or greater than
the route's prefix length.
The route shares the same most-significant bits (described
by prefix-length ), and the route's prefix length falls between
prefix-length2 and prefix-length3 , inclusive.
All the following are true:
The route shares the same most-significant bits
(described by prefix-length ) of the first destination
prefix.
The route shares the same most-significant bits
(described by prefix-length ) of the second destination
prefix for the number of bits in the prefix length.
The number of bits in the route's prefix length is less
than or equal to the number of bits in the second
prefix.
You do not use the through match type in most routing policy
configurations. For more information, see the JUNOS Policy
Framework Configuration Guide.
