Explanation could include the following:
- Loopback interface
- Routing loops
- Routing tables
- Static vs. dynamic routes
- Default route
- Distance vector routing protocols
- Routing Internet Protocol, version 2 (RIPv2)
- Hybrid routing protocols
- Border Gateway Protocol (BGP)
- Link state routing protocols
- Open Shortest Path First (OSPF)
- Intermediate System to Intermediate System (IS-IS)
- Interior vs. exterior gateway routing protocols
- Autonomous system numbers
- Route redistribution
- High availability
- Virtual Router Redundancy Protocol (VRRP)
- Virtual IP
- Hot Standby Router Protocol (HSRP)
- Route aggregation
- Routing metrics
- Hop counts
- Maximum Transmission Unit (MTU), bandwidth
- Costs
- Latency
- Administrative distance
- Shortest Path Bridging (SPB)
Process/Skill Questions:
- How would a router’s loopback interface be characterized? Is it virtual or physical?
- What does a routing table determine?
- What is a hop count?
