Re: a quick survey about LLDP and similar

[Eddie Parra]

+1 on it depends.  IMO, I would prefer LLDP vs. a vendor proprietary discovery 
protocol.  Where you intend to run it in your network is a major factor for 
risk.  

Also, you forgot to add LLDP-MED to #5 (but it might not be relevant to your 
services).

Re: Proving Gig Speed

+1 to Jared.  I’ve seen people not account for this when sizing CoS as well on 
Juniper.

Re: flow generating tool

[Eddie Parra]

If you are looking to automate any of your testing, +1 Ixia if the box
is using the Agilent OS/Interface (I forget how they are marketing it
now).  In regards to automation, I recently heard the Spirent
interface was quite handy for generating scripts from GUI
interactions, but I have not used it myself.

HTHs,

Re: OSPF Visualizer?

[Eddie Parra]

Lorell,

This project has not been updated in some time:

http://ospfviz.sourceforge.net/

If you want a commercial product, check out Packet Design's "Route
Explorer" (aka "REX")

HTHs,
