Greetings Wilson, While I haven't worked with IS-IS before but the only disadvantage I've encountered with OSPF is that it is resource intensive on the router it is running on which is why only one instance runs on any PE & P device on an ISP network. OSPF is pretty good in handling the core network routing while BGP & EGP handle the last-mile routing between PE & CE devices. BGP & EGP can run on top of OSPF. Warm regards, Michael.

Network Admins,
I Once went for an interview as a Core Network Admin in one of the major telcos in KE and asked which protocol i preferred and why.
Am sure am not the only one and won't stop here.
Though i gave my own reasons, a panelist insisted ISIS is superior and gave his reasons by grinning but not explaining to an interviewee [me of course]. Sadly i didn't get the job, probably because *i asked him* WHY he think isis is superior that OSPF :(
I came across this URL http://bit.ly/2bsqJCA when scrolling the web today, one year later - i still wanted to find out if am the only one who thinks its a matter of choice btwn the 2. Although there isn't distinct 1:1 argument, its good we discuss it here and figure out why one prefer one over the other - *consider a FLAT huge network.*
Kind Regards, Wilson./
