Question about OSPF LSA 5 and 7
Hi guys! one short question.. just a little doubt that's spinning in my head:
Why LSA 5 does not follow LSA 7 rules regarding the Forwarding Address? I mean, in LSA 7, there's always an IP Address in the Forwarding Address field, and it's the highest IP among the OSPF enabled loopbacks, and if none, highest OSPF enabled Interface.
But, LSA 5 gets an Forwarding Address of 0.0.0.0 if the External route resolves to a non-OSPF interface, so then it needs an LSA 4 so ABRs can show the world how to get to this route. How come it cant get a Forward address just like a LSA 7 (and translated LSA5)?
What am I missing :S?
