OSPF - LSA TYPE 1 AND 2
In this video we go into the operation details of the OSPF LSA 1 (router LSA) and LSA 2 (network LSA), what information they represent and contain and their impact on the general performance of the OSPF routing protocol
OSPF - CISCO LSA TYPE 1 AND 2
In this video we explore how to interpret the OSPF database on Cisco IOS devices focusing on LSA 1 and LSA 2, and analyzing how to manually build the topology information using this LSA
OSPF - LSA TYPE 3
In this session we explore in detail the operation of the Summary LSA (Type 3), what information they represent and contain, together with the details of how OSPF routers calculate the metric.
OSPF - CISCO LSA TYPE 3
In this session we explore how to interpret the OSPF database, focusing on the LSA type 3, how they are generated and the calculations that take place on OSPF Cisco IOS routers whit the information contained in the Summary LSA.
OSPF - LSA TYPE 4 AND 5
Details on how the OSPF LSA 4 (ASBR-Summary) and LSA 5 (External) operate and what information they contain. We'll take special attention into how the calculations are made to reach external routes.
OSPF - CISCO LSA TYPE 4 AND 5
In this session we explore how to interpret the OSPF database in Cisco IOS devices, focusing on LSA type 5 and type 4. We'll see in detail how the ASBR generates Type 5 LSA and how the ABR generate type 4 LSA
OSPF - LSA TYPE 7
Operation of LSA Type 7 on NSSA areas. How translation is performed by the ABR's from a LSA Type 7 to a LSA type 5 and the calculations performed with the forward address to get the metric to any specific route
OSPF - CISCO LSA TYPE 7
In this video we go through the steps needed to interpret the OSPF database on Cisco IOS devices focusing on the OSPF LSA type 7. We'll see in our configuration how the LSA type 7 is translated to a LSA type 5, the forward metric and metric types, how to check and calculate manually the metric, among other concepts
OSPF - CISCO COST MODIFICATION
In this session we will see how to modify and check the cost on Cisco IOS devices for the OSPF routing protocol (interface level and global configuration)
OSPF - BACKBONE AND REGULAR AREAS
In this session we analyze the operation of the area 0 (backbone) and regular areas, what optimization they provide and the benefit of using multiple areas
OSPF - STUB AND STUB NO SUMMARY AREAS
In this video we explore how stub and totally stub areas (stub no-summary) work, what OSPF LSA they filter and how OSPF provide connectivity to the routes that are lost with this LSA filtering
OSPF - NSSA AND NSSA NO SUMMARY AREAS
We explore in this session the operation of NSSA and totally NSSA areas (NSSA no-summary) what LSA types they filter, how Type 7 LSA are translated to Type 5 LSA and how routing is done within these areas
