Version 8.3.11.1 Introduced on the Z9000.
Version 8.3.8.0 Introduced on the S4810.
Usage
Information
LSAs are sent after the start-interval and then after hold-interval until the maximum interval is
reached. In throttling, exponential backoff is used when sending same LSA, so that the interval
is multiplied until the maximum time is reached. For example, if the start-interval 5000 and hold-
interval 1000 and max-interval 100,000 , the LSA is sent at 5000 msec, then 1000 msec, then 2000
msec, them 4000 until 100,000 msec is reached.
timers throttle lsa arrival
Configure the LSA acceptance intervals.
S4810
Syntax
timers throttle lsa arrival arrival-time
To return to the default, use the no timers throttle lsa command.
Parameters
arrival-time Set the interval between receiving the same LSA repeatedly, to allow
sufficient time for the system to accept the LSA. The range is from 0
to 600,000 milliseconds.
Defaults 1000 msec
Command Modes ROUTER OSPF

OSPFv3 Commands
Open shortest path first version 3 (OSPFv3) for IPv6 is supported on the S4810 platform.
The fundamental mechanisms of OSPF (flooding, DR election, area support, SPF calculations, and so on) remain
unchanged. However, OSPFv3 runs on a per-link basis instead of on a per-IP-subnet basis. Most changes were
necessary to handle the increased address size of IPv6.
The Dell Networking implementation of OSPFv3 is based on IETF RFC 2740.
