Figure 1-1 Router types Table 1-4 Router types Router Type Description Internal router All interfaces on an internal router belong to the same OSPF area. Area Border Router (ABR) An ABR belongs to two or more than two areas, one of which must be the backbone area. An ABR is used ...
Now, let’s talk about these OSPF LSA types detailly. Here, it is better to explain these LSA types with different area types and their LSA Adversisement requirements. So, the below diagram will be very useful for you. You can also view OSPF Packet Types Table of Contents OSPF Router LS...
Type 1 LSA include a list of directly connected network prefixes and link types. all routers generate type 1 LSA. Type 1 LSA are flooded within the area and do not propagate beyond an ABR. A type 1 LSA link-state ID(LSID) is identified by the router ID of the originating router. in...
Special areas can be configured to reduce the number of routing entries on the devices. Switches support four types of special areas defined in OSPF: stub area, totally stub area, NSSA, and totally NSSA. In most cases, routers in non-backbone areas on a typical OSPF network only need to ...

OSPF Multi-Area Lab 2 Posted on May 10, 2021 Ok so in this lab we want to tackle the concepts and configuration around OSPF areas. Now this is where OSPF can become challenging in my view, so let’s baby step through the area types and why we would ever want to do this. Basics...

The OSPF uses the following four types of routes (ordered by priority): l Intra-area route l Inter-area route l External route type 1 l External route type 2 Intra-area and inter-area routes describe the internal AS topology whereas the external routes describe how to select the route to...
