  1. What does BGP stand for and where is it primarily used?

    Answer: Border Gateway Protocol; used between autonomous systems on the internet

    BGP is the path-vector routing protocol used between autonomous systems and is the routing protocol of the internet.

  2. What is the purpose of ECMP (Equal-Cost Multi-Path) routing?

    Answer: To load-balance traffic across multiple paths with equal routing metrics

    ECMP allows a router to load-balance traffic across multiple equal-cost paths simultaneously, increasing throughput and redundancy.

  3. Which command on an Aruba CX switch shows the IP routing table?

    Answer: show ip route

    The show ip route command displays the IP routing table on Aruba CX switches, including route sources, metrics, and next-hops.

  4. What is route summarization (also called route aggregation)?

    Answer: Combining multiple specific routes into a single larger prefix to reduce routing table size

    Route summarization combines multiple contiguous specific routes into a single summary advertisement to reduce routing table size and LSA flooding.

  5. In OSPF, what triggers a Shortest Path First (SPF) recalculation?

    Answer: A change in the link-state database due to a new or changed LSA

    OSPF triggers an SPF recalculation whenever the link-state database changes due to a new, updated, or withdrawn LSA from any router.

  6. What is the difference between a routing protocol and a routed protocol?

    Answer: A routing protocol exchanges routing information between routers; a routed protocol is the protocol whose traffic is being routed

    A routing protocol like OSPF exchanges topology information between routers, while a routed protocol like IPv4 is the actual payload being forwarded.
