We use Cisco 3750 L3 switches for Metro Ethernet connectivity. The 3750 SFPs can run at wire speed up to 1 GiGE. The 3750s are very reliable, and have good, follow-the-sun technical support in case of problems. Some caveats: 1. only the ME version supports MPLS, in case you want to overlay an MPLS TE/VPN network on a Metro Ethernet Forum (MEF) ELAN raw Ethernet service. 2. If you are using IP multicast, make sure that the Metro Ethernet provider supports PIM snooping, otherwise (S,G) directed multicast packets will be flooded out all service provider ports that connect to your devices, emulating a 1993-style Ethernet hub. -----Original Message----- From: Mikael Abrahamsson [mailto:swmike () swm pp se] Sent: Monday, April 12, 2010 9:43 PM To: Jeffrey Negro Cc: nanog () nanog org Subject: Re: Router for Metro Ethernet On Mon, 12 Apr 2010, Jeffrey Negro wrote:

Get a used 3550 or a new 3400ME or something. Sounds likeyuou'll get by just fine using an L3 switch. -- Mikael Abrahamsson email: swmike () swm pp se
