Vyatta开源软件软件使用评测

　　T1 and T3 cards

　　VRRP and redundant power supplies in the server

　　Syslog and SNMP2c

　　Can use Ethereal (now Wireshark) to view packets going through the router

　　CLI, Web-based interface, Telnet, and SSHv2

　　The Community Edition--the standard Vyatta version--is free. However, there's no support included, and bug fixes are available only every six months.

　　Vyatta also offers the Professional Edition (starting at $497)and the Enterprise Edition (starting at $647) if support and priority bug fixes are necessary. You could use standard PC/server Ethernet cards (make sure they're supported), and you can buy the T1/T3 cards (or Ethernet cards) from Vyatta.

　　Of course, Vyatta also sells router appliances (i.e., servers with the Vyatta OS already installed). Starting at about $1,800, the appliance includes a Dell server, support, and the Vyatta router OS. This is much less than a comparable new Cisco router.

　　First impressions

　　While it's too soon for me to compare the full production functionality and features of Vyatta to a Cisco router, here's my initial experience with the Vyatta product. I downloaded the 96-MB file from Vyatta's Web site.
