■ Routes previously suppressed by a route map that are unsuppressed by this

command are not automatically advertised; you must use the clear ip bgp

command to perform a hard clear or outbound soft clear.

■ Example

host1(config-router)#neighbor berlin5 unsuppress-map inmap3

■ Use the no version to restore the default values.

■ See neighbor unsuppress-map.

set dampening

■ Use to enable BGP route flap dampening only on routes that pass the match

clauses of, and are redistributed by, a particular route map.

■ BGP creates a dampening parameter block for each unique set of dampening

parameters—such as suppress threshold and reuse threshold—used by BGP. For

example, if you have a route map that sets the dampening parameters to one

set of values for some routes and to another set of values for the remaining

routes, BGP uses and stores two dampening parameter blocks, one for each set.

■ Example

host1(config)#route-map nyc1 permit 10

host1(config-route-map)#set dampening 5 1000 1500 45 15

■ Use the no version to delete the set clause from a route map.

■ See set dampening.

Policy Testing

You can analyze and check your BGP routing policies on your network before you

implement the policies. Use the test ip bgp neighbor and test bgp ipv6 neighbor

commands to test the outcome of a BGP policy. The commands output displays the

routes that are advertised or accepted if the specified policy is implemented.

NOTE: You can use the standard redirect operators to redirect the test output to

network or local files. See the section JUNOSe System Basics Configuration Guide.

BGP routes must be present in the forwarding table for these commands to work

properly. If you run the policy test on incoming routes, soft reconfiguration (configured

with the neighbor soft reconfiguration in command) must be in effect.

NOTE: The output of these commands is always speculative. It does not reflect the

current state of the router.
