Hi WG,

RFC 5185 says that Neighbor's IP address to be encoded into Link Data field. 
Per RFC 2328 router's own IP address to be encoded into Link Data. What is the 
reason to advertise neighbor's IP address for multi-area links and not local IP 
address? It seems like bug. Could someone comment on this?

Advertising a neighbor address/ifindex helps to eliminate ambiguity in case of parallel point-to-point adjacencies. It's not perfect, but that's how it was specified. So it's not a bug.

thanks,
Peter
