Contact your account team for assistance if you have not done this before
for the first recommendation. If it's for an SP HQ-ed in North West Europe
or the Nordics then give me a call.
Look at IS-IS as an IGP, the TE features for MPLS are interesting, the IS-IS
IGP has been seen to scale to more routers per level, and the processing
overhead is less than that of OSPF.
Check Ivan Pepelnjak and Jim Guichards book from Cisco Press "MPLS & VPN
Architectures" ISBN 1-58705-002-1 for BCPs.

Subject: [nsp] ospf and bgp design question
hi, gangs
i am designing a SP's Network, total about 80 routers in one city,
including backbone nodes and access nodes, i have 2 questions:
1.which one is the better solution between multiple ospf areas and single
backbone area, and does it influence the MPLS VPN and TE? (ios version is
12.0.14S2).
2.if i use BGP route reflctor, how many clusters are fit? what does it lie
on?
any reply is appreciated
kevin
