Hello, Again for those reading Cisco Press' CCNP Routing Exam Certification Guide.
It's not clear to me how often the OSPF topology table is exchanged by default. I thought this happened every 30 minutes, regardless of other recent updates. The cert. guide is not consistent about this: Page 166: "...Although OSPF sends the entire table every 30 minutes after the last update, this is far less demanding of network resources than the older protocol, RIP. ..." Page 172: " ... However, 30 minutes after the last update was received, a compressed version of the table is propagated. ..." Page 185: "... OSPF will send summary information every 30 minutes, regardless of whether incremental updates have been sent in that time..." Page 186: "...Involves updates sent as required (when changes are seen) and every 30 minutes after no change has been seen..." Page 216: "... synchronized, incremental updates will be sent to the neighbors as soon as a change is perceived, as well as every 30 minutes...." Page 288: "...The topology table is exchanged between adjacent routers at least every 30 minutes..." Maybe one of the OSPF gurus knows this by heart, saving me some RFC reading and CCO searching time? Thanks, Eric Brouwers.
