From my understanding of statements made at Networkers by CCIE program managers, this isn't going to be a problem for you. They've said the CCIE lab is NOT a design lab and is NOT intended to test best current practices. For ease in grading, labs tend to have only one possible answer, so it will be quite clear in context whether they are looking for a RR or confed. To answer the question a little more broadly, not from the CCIE labs but from such things as the advanced ISPs workshops, for an ISP, RRs, including hierarchical clusters of RRs, are generally preferred for ISPs. They are simpler and somewhat easier to configure than confeds. Confeds do have a role, however, when you need, for example, to be able to set per-POP policy. For that reason, confeds are quite useful for ISPs that have acquired other ISPs with different design assumptions. Confeds are also useful for complex enterprise backbones-of-backbones. > >I'd like to hear comments about the pros and cons of each option in regards >to how Cisco might prefer to see implementation.
