Yes, one of the things I didn't get to in my NANOG presentation due to lack of time is the fact that we still have several AGS+es and a couple of 16Mbyte 7000s in the field. We have upgrades scheduled and RPs in hand for the 7000s, so they will be fixed soon. The AGS+es are currently not doing backbone routing, and are all being migrated into customer-access ASes so that they eventually will be able to default to the 64Mbyte 7000s doing backbone routing. The AGS+es eventually will be withdrawn as we will move customers attached to them to 64Mbyte 7000s. Anyway, the 16Mbyte routers that are out there now and participating in AS 1239 iBGP mesh (older boxes that antedate the current engineering plan) can and do keel over due to memory shortages. We have at least one multihomed customer in a similar situation. We appreciate several of our peers' efforts to keep routing tables small, and take defensive steps against those who do not. Sean. P.S.: Numbers wise SL/ICM has 14 AGS+es, one of which will be decommissioned and replaced with a 7010 tonight. There are five 7000s with 16Mbytes still and they will be upgraded soon. There are 25 64Mbyte routers turned up and active now, and a few others that in the being-installed phase, and considerably more on order and in the current engineering plan.
