Packet-forwarding.netOSPF – External routes Part 3: Type 7’s in single NSSA area.
Welcome back to part 3 about OSPF and external routes.
In this post I will focus on type 7 LSA’s. These are LSA’s thats created within an NSSA area. An NSSA area is, as you may know, an area which is meant as a stub area (no type 4 and 5’s), but will still allow for external routes to be introduced in the area.
