Class topic

Post 1. OSPF summary and concept

As the well-known link-state routing protocol, OSPF is a link-state routing protocol, which means, unlike distance vector routing protocol, it spreads link state advertisement instead of routing information. All the routers in the same area will maintain the same LSDB(link-state database)... More

Post 2. OSPF link types

In addition to defining the network type, OSPF also defines the link type, which is two different concepts. Link types are primarily used to describe the interfaces or neighbors of an OSPF router... More

Post 3. Introduction of the OSPF detailed LSAs

After the LSDB built up, the router can calculate the route path based on LSDB which includes multi types of LSA. From type 1 LSA to type 7 LSA, every type of LSA generated by different routers, and carries different link state messages... More

Post 4. OSPF external route cost and route selection

When OSPF imports external routes, the default cost is set to 1. For the same OSPF process, Type-1 external routes are preferred to type-2 external routes. For two Type-2 external routes, Compare the external cost... More

Post 5. HCIE Interview question – Typical Reasons for OSPF Neighbor Problems

Typical reasons for OSPF neighbor down usually include router-ID confliction, area-ID mismatch, authentication mismatch, hello/dead interval mismatch... More
