Configure LSA throttling timers
Configured LSA timers replace the standard transmit and acce4patnce times for LSAs. The LSA throttling
timers are configured in milliseconds, with the interval time increasing exponentially until a maximum
time has been reached. If the maximum time is reached, the system, the system continues to transmit at the
max-interval. If the system is stable for twice the maximum interval time, the system reverts to the
start-interval timer and the cycle begins again.
Enable passive interfaces
A passive interface is one that does not send or receive routing information. Enabling passive interface
suppresses routing updates on an interface. Although the passive interface will neither send nor receive
routing updates, the network on that interface will still be included in OSPF updates sent via other
interfaces.
Command Syntax Command Mode Usage
timers throttle lsa all
{start-interval | hold-interval |
max-interval}
CONFIG-ROUTER-
OSPF-id
Specify the interval times for all LSA transmissions
•
start-interval: Set the minimum interval between initial
sending and resending the same LSA.
Range: 0-600,000 milliseconds
• hold-interval: Set the next interval to send the same LSA.
This is the time between sending the same LSA after the
start-interval has been attempted.
Range: 1-600,000 milliseconds
• max-interval: Set the maximum amount of time the
system waits before sending the LSA.
Range: 1-600,000 milliseconds
timers throttle lsa arrival
arrival-time
CONFIG-ROUTER-
OSPF-id
Specify the interval for LSA acceptance.
• arrival-time: Set the interval between receiving the same
LSA repeatedly, to allow sufficient time for the system to
accept the LSA.
Range: 0-600,000 milliseconds
