Usage Guidelines When IS-IS receives a new LSP, it inserts it into the IS-IS database. If the LSP contains traffic
engineering TLVs, IS-IS flags the LSPs for transmission to the traffic engineering database. Depending
on the default or user-specified interval, traffic engineering TLVs are extracted and sent to the traffic
engineering database. Users can also specify the maximum number of LSPs that the router can process
immediately. Processing entails checking for traffic engineering TLVs, extracting them, and passing
them to the traffic engineering database. If more than 50 LSPs need to be processed, there is a delay of
5 seconds for subsequent LSPs.
The first 15 LSPs are sent without a delay into the traffic engineering database. If more LSPs are
re
ceived, the default delay of 5 seconds applies.
If you specify the no f
orm of this command, there is a delay of 5 seconds before IS-IS scans its database
and passes traffic engineering TLVs associated with flagged LSPs to the traffic engineering database
Examples In the following example, the router is allowed to process up to 50 IS-IS LSPs without any delay.
Router(config)# router isis
Router(config-router)# mpls traffic-eng scanner interval 5 max-f
lash 50
