Question/Term | Answer/Definition |
Primary Uses of Static Routing | Ease of routing table maintenance in smaller networks Routing to and from a stub network Accessing a single default |
Disadvantages of Static Routing | Not easy to implement in a large network Managing the static configs can become time consuming If a link fails, cannot reroute traffic |
Advantages of Dynamic Routing | Suitable in all topologies where multiple routers are required Generally independent of the network size Automatically adapts topology to reroute traffic if possible |
Disadvantages of Dynamic Routing | Can be more complex to implement Less secure. Additional config settings required to secure. Route depends on the current topology Requires additional CPU, RAM, and link bandwidth |
Data Structures | Routing protocols typically use tables or databases for its operations. Info kept in RAM. |
Routing Protocol Messages | Routing protocols use various types of messages to discover |
OSPFv2/3 Supports Link-State? | Yes |
OSPFv2/3 Routing Algorithm | SPF |
OSPFv2/3 Metric? | Cost |
OSPFv2/3 Areas? | Support the same two-level hierarchy |
OSPFv2/3 Packet Types? | Same Hello, DBD, LSR, LSU, and LSAck packets |
OSPFv2/3 Neighbor Discovery? | Transitions through same states using hello packets. |
OSPFv2/3 DR & BDR? | Function and election process is the same |
Router ID | 32-bit router ID: determined by the same process in both protocols |
IPv4 is for OSPFv? | 2 |
IPv6 is for OSPFv? | 3 |
How often are OSPF Hello packets sent by default? | 10 seconds on multi access and point-to-point segments. Every 30 seconds on NBMA. |
The Dead Interval? | 4 x as long as the Hello interval. |
What is needed for routers to become adjacent? | Their Hello & Dead intervals, network types and subnets much match. |
