• tag-value—(Optional) Enter a value to match the routes redistributed through a route map (1 to 65535).
Default) Not congured
Command Mode ROUTER-OSPF
Usage Information The no version of this command disables the summary address.
Example
OS10(config)# router ospf 100
OS10(config-router-ospf-100)# summary-address 10.0.0.0/8 not-advertise
Supported Releases 10.3.0E or later
timers lsa arrival
Congures the LSA acceptance intervals.
Syntax
timers lsa arrival arrival-time
Parameters arrival-time — Set the interval between receiving the LSA in milliseconds (0 to 600,000).
Default 1000 milliseconds
Command Mode ROUTER-OSPF
Usage Information Setting the LSA arrival time between receiving the LSA repeatedly ensures that the system gets enough time to
accept the LSA. The no version of this command resets the value to the default.
Example
OS10(config)# router ospf 10
OS10(conf-router-ospf-10)# timers lsa arrival 2000
Supported Releases 10.2.0E or later
timers spf
Enables shortest path rst (SPF) throttling to delay an SPF calculation when a topology change occurs.
Syntax
timers spf [start-time [hold-time [max-wait]]]
Parameters
• start-time — Sets the initial SPF delay in milliseconds (1 to 600000; default 1000).
• hold-time — Sets the additional hold time between two SPF calculations in milliseconds (1 to 600000;
default 10000).
• max-wait — Sets the maximum wait time between two SPF calculations in milliseconds (1 to 600000;
default 10000).
Default
• start-time — 1000 milliseconds
• hold-time — 10000 milliseconds
• max-wait — 10000 milliseconds
Command Mode ROUTER-OSPF
Usage Information By default, SPF timers are disabled in an OSPF instance.
Use SPF throttling to delay SPF calculations during periods of network instability. In an OSPF network, a topology
change event triggers an SPF calculation after a start time. When the start timer nishes, a hold time may delay
the next SPF calculation for an additional time. When the hold timer is running:
