My comment would be: That is simply matter of opinion and opinions may be swayed depending on the market that signs your check? :)
There have been a fair share of appliance bugs/sec vulnerabilities over the years as well. I agree software-based deployments have their flaws but I do not agree that it cannot be managed securely with comparable or exceeding uptime -vs- a drop in appliance. I firmly believe it has it's place in 'today's internet'. The question is where your expertise lies and what you expect to get out of it. If your background is Cisco and you have a good relationship then I wouldn't fix what isn't broken. I have very little experience with Vyatta other than doing some mild testing. I am simply speaking more to the 'software-based' market like Vyatta/BSD. -----Original Message----- From: Truman Boyes <tru...@suspicious.org> Date: Tue, 13 Jul 2010 16:56:16 To: Dobbins, Roland<rdobb...@arbor.net> Cc: NANOG list<nanog@nanog.org> Subject: Re: Vyatta as a BRAS On 13/07/2010, at 4:50 PM, Dobbins, Roland wrote: > > On Jul 13, 2010, at 1:34 PM, Sharef Mustafa wrote: > >> do you recommend it? > > > My comment would be that a software-based BRAS - 7200, Vyatta, et. al. - is > no longer viable in today's Internet, and hasn't been for years, due to > security/availability concerns.

Mencken I agree. In a bind I have seen small providers experiment with FreeBSD/Linux L2TP termination (as a LNS), I would recommend against it if you have a business that depends upon these customers' happiness. There were all sorts of issues to address when the customer ran significant traffic forwarding through the unix boxes, namely adjusting kernel parameters for NMB_CLUSTERS, heap sizes, all sorts of sysctl parameters, adding additional interface counts, etc. A low cost 7200 or ERX-310 would easily fit the bill, and you can buy them cheap these days.
