[j-nsp] LDP Interop with IOS

[Brad Fleming]

Thanks very much for all the replies.

Unfortunately the issue was 100% operator error. I somehow overlooked the lack of "ip ospf 2495 area 0.0.0.0" under the Cisco's loopback0 interface. Once I dropped that on the interface and cleared OSPF processes my LDP neighbors came online correctly. Jez.... should have been the first thing I checked.

Sorry to waste time, bits, and disk space on such a simple problem. Thanks again for replies though!
