I dont understand why anyone would recommend a Cisco 36xx on a freebsd list! Get zebra, a dual port card and 128M of ram and run freebsd 3.4. Works like a charm. we have people running dual full T3s, so its not like its a stretch. We also have a complete 1U solution for this at www.etinc.com/t1rm.htm Dennis At 07:58 AM 3/20/00 -0500, Troy Settle wrote: > >A 2503 will not take a 2 full tables.
