The night before last I had to upgrade our router because the floppy containing the boot code and configuration died. Drive would not respond so the router would not boot. So I took the opportunity to install a new CEC (basically the brains of the unit) which has two faster CPU's, and a flash-rom drive. Because I couldn't read the old configuration I had to configure this router from scratch. And there were a few things I missed. Some of the things I initially missed include: LMI configuration for the frame relay link which resulted in the lack of working congestion control and this seemed to negatively impact at least one customer. RIP configuration between the router and the communications servers used for the v.34 dialups resulted in routes not being propogated for dial up PPP connections on the V.34 lines. Filters misconfigured somewhat caused some problems for mail SMTP connections. Hardware with nothing connected enabled caused stability problems. All of these things have been resolved. Sprint has moved the due date for the third T1 to 6/18, but we're all ready for it now, DSU/CSU is connected and ready to go as soon as it's turned up. I loaded new software for the router at the same time I upgraded the hardware, and it has support for expanded firewall capabilities, and expanded ATM capabilities, and DHCP server. These capabilities were the reason we needed the Cisco which has not yet arrived for the DSL connection. I'm going to connect the DSL port to this router and see if we can get it to talk. It would be preferable to have it in the same router because it eliminates an extra hop and an extra opportunity for things to go wrong, and it also provides no location to intercept (sniff) packets. And of coarse if I don't need a $5000 router with a command set I'm not familiar with that's only a plus! At some point in the not to distant future we'll be moving from FDDI backbone to 100-base-T backbone.
