So we stick to OSPF, because no one wants to complicate things, unfortunately as we integrate more services, I doubt we will sustain the current architectures.
In large scale proper MPLS networks.IS-IS supports TE integrationIS-IS uses tlvs which makes it easier to extend it capabilities.Can handle both IPv6 and IPv4That said none of the kenyan ISP I have seen have P routers, Just interlinked PE routers. No carrier supporting carrier integrations, no interprovider MPLS customers, no multicast MPLS integrations and hence my earlier comments.

However there could be reasons why one would prefer one IGP over the other:
1. Provider network environment - do all you equipment support the IGP? Vendor support for the IGP in relation to MPLS TE and other technologies you want to support.
Huh! you mean vendor cool-aid? Best of luck!.2. Availability of technical expertise for the IGP
Perhaps. But if an engineer understands the concepts the IGP can always be learned in a short while.3. Ease of deployment and scaling. ISIS is easier to deploy and scale on IPv4/IPv6 dual stack environment compared to OSPF which requires separate processes and area design.
A good engineer is a lazy engineer ;)It's a matter of organization choice in my opinion
I tend to think it is boils down to either the vendor influence for large networks and comfort of the lead network engineer/CTO for medium to small networks.Regards,Michuki.
