[c-nsp] EIGRP as core routing protocol on MPLS network

[Kris Price]

Hi,

I've been trying to find out the implications of using EIGRP to 
distribute the loopbacks for a BGP/MPLS network instead of the usual 
OSPF or ISIS. But either it isn't a very well covered topic or my 
Google-foo is seriously bad.

I've lab'ed it up in a very simple environment and for typical Layer 3 
BGP/MPLS VPN applications everything seems to work fine as expected, LDP 
continues distributing labels, and VPN packets are label switched across 
the network.

However, I assume the caveats are around using features that use 
OSPF/ISIS for transporting additional information or for signalling, 
e.g. perhaps taffic engineering info.

Given there is no information on this on Google I guess it isn't 
supported and the recommendation is simply "don't do it".

But I'm curious, so has anyone done this in a production environment for 
any reason, or has anything enlightening to say on the matter?

Cheers
Kris

PS: before anyone asks "Why on earth would you want to do that!?" I 
don't particularly, but I'd like to know about it for arguments sake.
