My bad -- you're entirely right. I was thinking of triggered updates,
which are useful even if the peer doesn't implement them. The
on-demand extensions to RIP are almost completely unrelated, and
I agree with you that they are probably useless nowadays.
Arjun -- if you're thinking of tackling a Quagga-related project, then
adding triggered updates (RFC 2453 paragraph 3.4.4, RFC 2080 paragraph 2.5.1)
to Quagga's implementations of RIPv2 and RIPng would be a worthy endeavour.
The on-demand extensions to RIP, on the other hand, are of very
doubtful utility nowadays.

Last time I checked, Quagga didn't. 8 minutes to reconverge after you
lose a route :-/
