OSPF -vs- ISIS

Tue Jun 21 14:04:34 UTC 2005

All,

Can anyone point me to information on what the top N service providers
are using for their IGP? I'm trying to build a case for switching from
OSPF to IS-IS. Those on this list who are currently running IS-IS, do
you find better scalability and stability running IS-IS than OSPF? I
understand that this question is a lot more complex than a simple yes
or no since factors like design and routing policy will certainly
affect the protocols behavior.

Any insights or experiences that you can share would be most helpful.

Thanks,
