Correct Answer by Edison Ortiz about 8 years 11 months ago

In my CCNP days, there was no such thing as dynamips so I can't really offer much guidance as to the extend of help this product can provide.


However, I must say, it should help you around 80% to 85% of the general task. The 15% to 20% is mostly due to switching but you should be able to perform 100% of routing tasks.


For switching task which you can't do in dynamips, I recommend renting a rack for a day or two. They are quite cheap. Just google for 'CCIE Rental Racks'.

My Dynamips:


Rack1SW1#sh ver | i IOS

Cisco IOS Software, 3600 Software (C3640-IK9S-M), Version 12.4(17), RELEASE SOFTWARE (fc1)

Rack1SW1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Rack1SW1(config)#spanning-tree ?

backbonefast Enable BackboneFast Feature

portfast Spanning tree portfast options

uplinkfast Enable UplinkFast Feature

vlan VLAN Switch Spanning Tree


Rack1SW1(config)#spanning-tree




As you see, I have uplinkfast and backbonefast available.


Can I change the mode to RSTP? No.


But I have the features available that makes up RSTP.


BTW, you are only available to run CST (Common Spanning Tree) on Dynamips not PVST nor RPVST.


HTH,
