2 cents
If you planning big network , IGP ospf or ISIS to carry CORE routes. BGP to
carry your different VRFs.
But if you stick to enterprise level then IGP ospf should work fine.

Subject: [OSL | CCIE_RS] Best IGP for an MPLS backbone
So, I had an interesting discussion about this issue with my colleagues today.
Some of them think that wee should use OPSF, others IS-IS. My opinion is that
we shoul use BGP.
Our backbone topology is something like:
P1----------P2--------P3 | | | | |
| | | |P4----------P5--------P4
Each p2p P-to-P lilnk is a /30.
>From my point of view, an issue that could rise using IS-IS or OSPF, is the
>LDP/IGP synchronization. In the OSPF case, there is the LSAs issue too.
>Although Cisco's IOS has an LDP-IGP synchronization feature, I am still not
>comfortable to use it in a such critical environment.
In other hand, some of my colleagues point that it's no scalable to use BGP as
IGP.
What are your thoughts ?
This is a new project and we are still planning it. If you guys could point
some research (books, sites and so on) I'd appreciate that.
TIA
