hi,
when should an spf be run, there are several events which cause
the spf to be scheduled. i feel the rfc doesn't talk about it clearly. i
want
to know all the cases which leads to the scheduling of spf, and running spf
eventually and i have the following questions.
1. when an interface state changes, should the spf be run immediately
or should i originate the router lsa and then run it.
2. what happens when an interface state change happens while spf is running.
3. what happens when a new lsa is received while spf is running.
4. should i run spf while one of my neighbor is in the process of dd
exchange.
i think there are awful lot of scenarios, i'm relatively new to ospf. i want
to
understand all the scenarios of spf scheduling (running) and the best way to
do it.
by bestway i mean, for example, if an interface state changes, is it good
to do spf right after i originate the router lsa or should i wait for some
time expecting i might receive some new lsas from my neighbors
because of my router lsa change.
please shed some light.
thanks
