[j-nsp] OSPFv3 interop/tuning recommendations?

[Justin M. Streiner]

All:

I have a fairly extensive IPv6 test bed set up in my lab, using OSPFv3 
as my IGP, and one thing I noticed is that the OSPFv3 adjacencies on links 
between Cisco (6509-Es, Sup720/3BXLs, 12.2SXH code) and Juniper (M7is, 
JUNOS 10.3R1.9) devices seem to take about 3x longer to come up, 
than between two Cisco devices.  OSPFv3 timers are at their default 
settings on all devices.  The topology is point-to-point links, and 
all of the relevant devices are in the same area.  OSPFv3 adjacencies 
between two Juniper devices also seem to come up pretty quickly.

It's been a while since I've had to look at IGP interoperability between 
the vendors, so I still need to re-familiarize myself with timer 
differences between vendors and things like that, to understand why the 
Cisco<->Juniper adjacencies come up more slowly.

It's not a major headache at this point (~30 secs to bring up a 
Cisco<->Juniper OSPFv3 adjacency vs ~10 secs to bring up a Cisco<->Cisco 
adjacency, and ~2 secs to bring up a Juniper<->Juniper adjacency), but 
something I'd like to understand fully and address before I start rolling 
things out in production down the road.

Does anyone have any recommendations for tuning OSPFv3 in multi-vendor 
setups like this?

Thanks
