neighbor advertisement-interval (BGP and BGP4+)
Use this command to set the minimum interval between sending iBGP or eBGP routing
updates for a given route. This command reduces the flapping of individual routes.
Use the no variant of this command to set the interval time to the default values
(30 seconds for eBGP peers and 5 seconds for iBGP peers) for a given route.
Syntax [BGP/BGP4+] neighbor <neighborid> advertisement-interval <time>
no neighbor <neighborid> advertisement-interval [<time>]
Default [BGP/BGP4+]
The default interval between sending routing updates for a given route to eBGP peers is
30 seconds, and the default interval for a given route to iBGP peers is 5 seconds.
Mode [BGP/BGP4+] Router Configuration
Usage [BGP/BGP4+] Use this command to set the minimum interval between sending iBGP or eBGP routing
updates for a given route. To reduce the flapping of routes to the internet, set a minimum
advertisement interval, so iBGP or eBGP routing updates are sent per interval seconds.
BGP dampening can also be used to control the effects of flapping routes. See the bgp
dampening (BGP and BGP4+) command in this chapter, and the BGP and BGP4+ Route
Dampening section in the BGP and BGP4+ Introduction chapter for more information.
The advertisement-interval time value is the minimum time between the advertisement
of Update messages sent from a BGP speaker to report changes to eBGP or iBGP peers.
This is the minimum time between two Update messages sent to iBGP or eBGP peers.
See the neighbor as-origination-interval (BGP and BGP4+) command to set the
interval time between messages to iBGP peers, which have prefixes within the local AS.
Use this command instead of the neighbor as-origination-interval (BGP and BGP4+)
command for eBGP peers with prefixes not in the same AS and updates not in a local AS.
Parameter Description
<neighborid> {<ip-address>|<ipv6-addr>|<peer-group>}
<ip-address> Specify the address of an IPv4 BGP neighbor,
in dotted decimal notation A.B.C.D.
<ipv6-addr> Specify the address of an IPv6 BGP4+
neighbor, entered in hexadecimal in the
format X:X::X:X.
<peer-group> Enter the name of an existing peer-group. For
information on how to create peer groups,
refer to the neighbor peer-group (add a
neighbor) (BGP and BGP+) command on
page 3.144, and neighbor route-map (BGP
and BGP4+) command on page 3.159. When
this parameter is used with this command,
the command applies on all peers in the
specified group. Note that if you apply an
advertisement-interval value to a peer group
it will apply to all members in the peer group.
<time> <0-600> Advertisement -interval value in seconds.
