Allied Telesis VERSION 5.4.3-2.6 manual Neighbor as-origination-interval BGP and BGP4+, Ipv6-addr

BGP and BGP4+ Commands

neighbor as-origination-interval (BGP and BGP4+)

Use this command to adjust the sending of AS (Autonomous System) origination routing updates to a specified iBGP peer. This command adjusts the rate at which updates are sent to a specified iBGP peer (15 seconds by default). You must set a rate when you enable it.

The as-origination-interval is the minimum time set between the advertisement of Update messages sent from a BGP speaker to an iBGP peer to report changes within the local AS.

Use the no variant of this command to reset the timer to the default value of 15 seconds.

Syntax [BGP]	neighbor <neighbor_address> as-origination-interval <time>
	no neighbor <neighbor_address> as-origination-interval [<time>]
Syntax [BGP4+]	neighbor <ipv6-addr> as-origination-interval <time>
	no neighbor <ipv6-addr> as-origination-interval [<time>]
	Parameter	Description
	<neighbor_address> Specify a neighbor IPv4 address, in dotted decimal in the
		format A.B.C.D.
	<ipv6-addr>	Specify an address of an IPv6 BGP4+ neighbor, entered in
		hexadecimal in the format X:X::X:X.
	<time>	<1-600>Time in seconds.
Default [BGP/BGP4+]	The default interval between sending routing updates to iBGP peers, which include a
	prefix that originates from the local AS, is 15 seconds by default.
Mode [BGP/BGP4+]	Router Configuration
Usage [BGP/BGP4+]	This command is used to change the minimum interval between sending AS-origination
	routing updates. The update interval for iBGP peers can be set from 1 to 600 seconds.

For interoperability with other vendors’ devices, we recommend using the default value. The AS origination interval timer may not be available to adjust on other vendors’ devices. Applying the default of 15 seconds across the AS maintains a common timer policy.

AlliedWare Plus devices use the default 15 second AS Origination Interval timer as per RFC 4271, a 30 second keepalive timer, a 90 second hold timer, a 120 second connect timer, a 5 second iBGP peer route advertisement interval, and a 30 second eBGP peer route advertisement interval.

Cisco devices use a 60 second keepalive timer, a 180 second hold timer, and no iBGP peer route interval timer (0 ). Juniper devices use a 10 second AS Origination Interval timer.

The as-origination-interval time value is the minimum amount of time between the advertisement of Update messages sent from a BGP speaker to report changes within the local AS. This is the minimum time between two Update messages to iBGP peers, which contain a prefix that originates from the same AS. See the neighbor advertisement- interval (BGP and BGP4+) command to set time between messages to eBGP peers.

Use this command instead of the neighbor advertisement-interval (BGP and BGP4+) command for iBGP peers with prefixes in the same AS for updates only within a local AS.
