In large scale proper MPLS networks.

IS-IS supports TE integration
IS-IS uses tlvs which makes it easier to extend it capabilities.

Back when i ran networks early 2000s and had 3 x 9600 baud-rate modems between Malindi and Mombasa. IS-IS TE integration would have worked great for me. Today when i have 1G and 10G ports between cities and ability to create LAGs on switches. Yet despite the lack of IS-IS TE, OSPF was rock solid in load balancing traffic across the 3 links.

Points well noted.

Can handle both IPv6 and IPv4

So does OSPFv3 :). not so direct though. But it does.

That 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.

Seriously ... do customers pay extra for these solutions ?.
