Understanding OSPF Type-4 LSAs

In this video you will learn about the OSPF type-4 summary ASBR LSA. We will examine why we need this LSA and look at a scenario on real cisco equipment to demonstrate the type 4 LSA

@starguard: Link-State Advertisement. Essentially it is an advertisement containing the relevant link and state information needed for OSPF routers to build a topology database which they then use to build their routing table

What kind of device is that Cat3? i cant find it in Packet Tracer.

You know how Cisco likes to make proprietary protocols like EIGRP easier and more flexible to work with? I wish they could do the same thing with OSPF.

Ok I understand, that we know how to get to 4.4.4.4 .. But if we advertise the loopback 4.4.4.4 into ospf, , it wud be reflected in all areas.. wudnt it??

[shaheershaikh]

wudnt R2 have a type 3 LSA of 4.4.4.4? If R2 had it in the first set up, , it means 4.4.4.4 has been advertised in ospf.. Correct me if I am wrong..
