Juniper BGP - CONFIGURATION GUIDE V 11.1.X User Manual

■ Use to match a route for the specified route type.
■ Example
host1(config)#route-map nyc1 permit 10
host1(config-route-map)#match route-type level-1
■ Use the no version to delete the match clause from a route map or a specified
value from the match clause.
■ See match route-type.
match tag
■ Use to match the tag value of the destination routing protocol.
■ Example
host1(config)#route-map 1
host1(config-route-map)#match tag 25
■ Use the no version to delete the match clause from a route map or a specified
value from the match clause.
■ See match tag.
neighbor route-map
■ Use to apply a route map to incoming or outgoing routes.
■ If you specify an outbound route map, BGP advertises only routes that match at
least one section of the route map. For routes that do not match, no further
processing takes place with respect to this peer, and those routes are not
advertised to this peer. The nonmatching route is still in the BGP RIB and can
be sent to other peers depending on the outbound policy applied to those peers.
■ If you specify an inbound route map, BGP processes only the received routes
that match at least one section of the route map. The nonmatching routes are
rejected from entering the local BGP RIB and no further processing takes place.
■ A clause with multiple values matches a route having any of the values; that is,
the multiple values are logical ORed.
■ If you specify a BGP peer group by using the peerGroupName argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer. However, you cannot
configure a member of a peer group to override the inherited peer group
characteristic for outbound policy.
■ New policy values are applied to all routes that are sent (outbound policy) or
received (inbound policy) after you issue the command.
To apply the new policy to routes that are already present in the BGP routing
table, you must use the clear ip bgp command to perform a soft clear or hard
clear of the current BGP session.
Behavior is different for outbound policies configured for peer groups for which
you have enabled Adj-RIBs-Out. If you change the outbound policy for such a
peer group and want to fill the Adj-RIBs-Out table for that peer group with the
