Here's a list of the major features I'll be lacking with Dynamips, and they are significant:
- No ISL trunking
- No bpdu-guard on interfaces
- No QinQ trunking
- No private VLANs
- No PAgP / LACP
- Cannot set switch ports to nonegotiate
- lose some STP features, like bpduguard, bpdufilter
- No MSTP
- No layer 3 port-channel
- No Switch Database Templates
- No udld
- No port security
- No port protected
- lose some qos specific configuration of hardware queues like srr-queue
- No extended VLANs, unless transparent mode
- Can't modify prune-eligibility of ports
I'll still prefer to rent racks to get practice. Luckily, http://www.gradedlabs.com/ is pretty cheap!
Ya the racks seem like a good idea to me compared to dynamips.
ReplyDeleteI'm currently working on building a free online network simulator. While I still have a long way to go, I did take note of all the things you listed above so that I can be sure to implement them. My goal is to have something online that is free to use, but will give you the same functionality as CCIE lab.
