Example
host1(config-router)#
neighbor 192.168.1.158 capability orf prefix-list both
•
Use the
no
version to prevent advertisement of the capability. Use the
default
version
to restore the default, advertising the capability.
•
See neighbor capability.
neighbor maximum-orf-entries
•
Use to set the maximum number of ORF entries of any one type that will be accepted
from the specified neighbor.
•
Example
host1(config-router)#
neighbor 192.168.1.158 maximum-orf-entries 125000
•
Use the
no
version to restore the default value of no limits.
•
See neighbor maximum-orf-entries.
neighbor prefix-list
•
Use to assign an inbound or outbound prefix list.
•
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.
•
Example
host1(config-router)#
neighbor 192.168.1.158 prefix-list seoul19 in
•
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 results of the new
policy, you must use the
clear ip bgp peer-group
command to perform a hard clear or
outbound soft clear of the peer group. You cannot merely perform a hard clear or
outbound soft clear for individual peer group members because that causes BGP to
resend only the contents of the Adj-RIBs-Out table.
•
Use the
no
version to remove the prefix list.

See neighbor prefix-list.
Configuring Route Flap Dampening
Route flap dampening is a mechanism for minimizing instability caused by route flapping.
Route flapping
occurs when a link is having a problem and is constantly going up and
