Question 1

An Aruba switch is running OSPF. Which LSA type is generated by an ABR to describe routes from one area to another?

Accepted Answer

ABRs generate Type 3 Summary LSAs to advertise inter-area routes between OSPF areas.

Question 2

What is the administrative distance of OSPF on an ArubaOS-CX switch by default?

Accepted Answer

110

Answer

OSPF has a default administrative distance of 110 on ArubaOS-CX switches.

Question 3

Which OSPF network type does ArubaOS-CX assign to an interface configured as a point-to-point link?

Accepted Answer

Point-to-point

Answer

ArubaOS-CX assigns the point-to-point OSPF network type to interfaces connecting exactly two routers, eliminating DR/BDR election.

Question 4

A network engineer needs to prevent an ArubaOS-CX switch from becoming the OSPF DR on a broadcast segment. What is the most reliable method?

Accepted Answer

Set the OSPF priority to 0

Answer

Setting the OSPF interface priority to 0 makes the router ineligible for DR/BDR election.

Accepted Answer

show ip ospf neighbor

Answer

The 'show ip ospf neighbor' command displays neighbor states, including whether adjacency has reached FULL.
