message-digest-key Message digest authentication password (key)
priority Router priority
Router(config-if)#ipv6 ospf ?

yes you have to know all of that. you have to troubleshoot why routers aren't establishing OSPF adjacencies from the OSPF commands and routing tables

so authentication,authentication key, hello dead interval configuration in IPv4
and neighbor configuration command in IPv6 is part of ccent syllabus ?
why adjacencies are not formed that I know missmatch hello dead interval auth etc
so he only reason I need to know these commands is to enable matching so that
routers can become adjacent ? -

If they're asking for these commands on CCNA then it's likely that companies change these intervals to speed-up convergence time.
By contrast, since Cisco isn't asking for EIGRP K-values on the exam, they don't find it all that likely that the junior admin will encouter K-value changes in the wild in EIGRP deployments. -

Exam objectives can be located here. This should help clarify things.

Those are the CCNA 200-120 objectives not ICND1 100-101 objectives.

OSPF is also covered in the ICND1 objectives as well. They included some of it as an objective in there, all about single area OSPF.satishtech wrote: »Those are the CCNA 200-120 objectives not ICND1 100-101 objectives.Working on CCENT and nearly almost there. Retake in December and pass, then after that, study for ICND2 and work on CCNA Security and look into Microsoft certifications. No previous IT certs.

Well the question wasn't directed at a particular exam. And the CCNA objectives are the same regardless of taking one exam VS two.
