OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is configured with this range for Area 1: 10.10.0.0/17. Which type of issue occurs due to this…
The correct answer is C. The ABRs advertise routes inconsistently, and they could potentially introduce a routing loop. See the full explanation below for the reasoning.
Question
OSPF Area 1 has two ABRs. One ABR is configured with this range for Area 1: 10.10.0.0/16. The other ABR is configured with this range for Area 1: 10.10.0.0/17.
Which type of issue occurs due to this mismatch?
Options
- AThe ABRs lose routing entropy and cannot route traffic between each other at all.
- BThe ABRs create a discontinuous area and disrupt intra-area routing between devices within Area 1.
- CThe ABRs advertise routes inconsistently, and they could potentially introduce a routing loop.
- DThe ABRs lose adjacency in Area 1 and must route all traffic to each other through Area 0.
