OSPF tutorials help

Was wondering what resources there are for learning OSPF as I would like to add to my arsenal of knowledge in the dynamic routing domain, so far which only consists of knowledge of babel.

And seeing as I’d like to possibly conjoin CTWUG and CRXN (by having both OSPF daemons and babel dump and share the kernel routing table) it would be a good start to understand how things currently work on the network and the wiki seems broken in some places so I thought it would be best to ask here.

OSPF on the Linux proper side I could do via Bird and then on Mikrotik I know they have it pre-packaged
