The interesting products now are the IP/SONET OC3c card and the OC12 card that should turn up one day.
They are available, we are using them at the moment and so far not a dropped packet.
The attraction to us for buying this product is the BSDi OS used at the management controller. We have somewhat unusual requirements, including our own internal protocol for dynamic routing of dialups, and the availability of the BSDi environment behind Ascends new CLI makes this one of the few real routers that works off the shelf.
Indeed, using gated on this box rules.
We currently have one in house, and once some SNMP issues are fixed we will be able to complete testing and then maybe buy some.
As to who is using them in a production environment, I understand from colleagues that a recent "supercore" upgrade that PSI did in NY (where we peer with them) was to roll out one or more GRF's. This is of course unconfirmed rumour until someone from PSInet speaks up.
