It has been about 5 years since I used cisco equipment so I am quite rusty, plus I am no expert. So what I need is the follow and if there is a better option then please suggest.
We have a Cisco 1721, which is being configured by the ISP so that the two ISP links will rollover. BGP I believe is what they are doing.
I also have a 3COM Baseline 2250, and want to setup two VLANs on that. VLAN 1 will have all the client and internal systems. And VLAN 2 will be for the public servers. The have some hosted services running on them for clients. And we have a total of 16 public IP's available.
What I want is to setup VLAN routing on the router so that both VLAN's can communicate. My understanding is that this is the 802.1q spec, and the switch does support it.
How do I go about setting this up, or is there an article I can refer to for setup. Also, what I have researched so far, it seems like I just give the ethernet port on the router to subinterfaces with an IP for each VLAN. If someone could let me know if this is on track or not.
