I think that a full routing table takes about 6 MB these days. The Cisco 2501 comes with 2 MB and you can add 16 MB for something like $300 if you don't buy the SIMM from Cisco. Use one Cisco to handle one feed and the other Cisco to handle the other feed. If you get a lot of route flaps, increase the dampening. This approach saves money and gives you real fault-tolerance. Either provider or either Cisco can fail and you won't go down. I would also put them on separate UPSs. -- Jim Dixon VBCnet GB Ltd +44 117 929 1316 fax +44 117 927 2015 http://www.uk.vbc.net VBCnet West +1 408 971 2682 fax +1 408 971 2684
