Trunking must use a Fast Ethernet or Gigabit Ethernet port, however you can use simple access links (non-trunking connections) to a single 10 Mbps Ethernet port on a router. The number of VLANs the router can route is dependent upon the number of interfaces the router has. Each VLAN requires its own dedicated 10 Mbps Ethernet port. -- Leigh Anne -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tony Medeiros Sent: Wednesday, August 22, 2001 4:06 AM To: [EMAIL PROTECTED] Subject: Re: Problem Using external routers to route between VLANs [7:16786] As far as I know, trunking MUST be on at least a fast ethernet interface. Another way out is put an NM-1E ethernet module on your 2610 and put each interface in a different vlan. Or buy a 2620. I hate to say this, but, this has been gone over AT LENGTH over the last few months. Sorry to be the bearer of bad news.
