Hi there, Cisco Press' CCNP Routing Exam Certification Guide advises to place an ASBR in the backbone area (p. 290, chapter 6):
"... If there is any redistribution between other protocols to OSPF on a router, it will be an ASBR. Although you can place this router anywhere in the OSPF hierarchical design, it should reside in the backbone area. Because any traffic leaving the OSPF domain will also likely leave the router's area, it makes sense to place the ASBR in a central location that all traffic leaving its area must traverse..." I find this a strange design guideline. I would rather prefer to connect an external network to the edge/distribution layer in an OSPF area different to the backbone area. As a consequence redistribution would happen outside the backbone area... What's your view on this?
