#CCENT and #CCNA candidates need to be comfortable with VLSM. The previous post gave you a chance to exercise; today’s post lets you check your answers to the first part of VLSM design drill 2. Of course, reading the original
For this final variation of a #CCNA Simlet question in this series, consider what happens when one OSPF neighbor changes its OSPF Hello interval. Based on what you expect to change, what show command output should change? Prep for those
The boss of our #CCNA is at it again today with another VLSM project. The scenario helps you exercise your brain in a VLSM world. As with all the VLSM design drills, you are given an existing internetwork with some pre-existing
The #CCNA scenario begins with a working router triangle, using a single OSPF area. Then you shutdown a serial link. What changes with OSPF show command output? Show ip ospf neighbor? Show ip ospf interface brief? Show ip route? And
More VLSM work for #CCENT and #CCNA today! Today’s post is simple enough: this post wraps up the answer to the VLSM design drill posted earlier. Dive right in! Here’s the list of earlier posts in this exercise: The original
Time for some VLSM work for #CCENT and #CCNA today! Today’s post begins the analysis for the VLSM design drill posted earlier. The original post posed a scenario, with an existing subnet design that uses VLSM. Your job: plan a new
VLSM causes many #CCENT and #CCNA candidates much heartache. Today’s post shows a VLSM design exercise that is useful for exam prep as well as real life. The idea: begin with an existing design that happens to use VLSM. Then
OSPF fails – a little – on a #CCNA Sim question. What show command symptoms would you expect to see if the misconfiguration was that a WAN interface between two routers was shutdown? What if redundancy exists over some other
The last post set up a #CCNA troubleshooting drill. Today, we’ll walk through the analysis. What were your predictions? On which routers (R1, R2, and R3) do you expect to see a change to the output of show ip ospf
