RE: Looking for information on IGP choices in dual-stack networks

[Sameer Khosla <skhosla () neutraldata com>]

Think of scenarios where you have mergers/acquisitions where different portions of the now amalgamated network were 
designed differently and there may be too much pain or require too much time to redesign rather than bolt together and 
redistribute.

that confuses me, the logic I mean...

I suppose in a single network I'd expect to see one igp for an address family (ospf or ospfv3). Not "eastcoast devices 
do ospf (stodgy
bastards!) and westcoast goes isis!"
