Hi,
I would like to understand the scenarios wherein the service
provider/network admin might run both ISIS and OSPF together inside their
network. Is this something that really happens out there?
One scenario that i can think of when somebody might run the 2 protocols
ISIS and OSPF together for
Ospf offered as Pe-ce protocol to L3 mpls vpn customers and Isis as IGP for
MPLS Core.

When you might run OSPFv3 (for IPv6) and ISIS (IPv4) together because you
have equipment that is buggy for ISIS multi topology.

One scenario that i can think of when somebody might run the 2 protocols
ISIS and OSPF together for a brief period is when the admin is migrating
from one IGP to the other. This, i understand never happens in steady
state. The only time this can happen is if an AS gets merged into another

Glen,
One transition scenario you noted below is often a use case. I have seen
networks move from OSPF to IS-IS (more cases then the reverse).
In those cases, the overlap period may not be very short (years vs.
weeks/months).
I have also seen some use one protocol (which I think was mentioned

Victor,
Folks could, at least theoretically, use ISIS or OSPF multi instance/multi
topology extensions to support IPv4 and IPv6 topologies. This way they
would only need to run a single protocol and thereby requiring expertise in
handling only one protocol.
With whatever i remember, OSPFv3 can
Glen,
Yes, if you are referring to RFC5838 like functionality in OSPFv3 (AF
support) that is correct. I personally don't have experience with that mode
of operation (as the networks I had experience with went dual stack a while
back).
I guess someone looking to dual stack now may want to
