[c-nsp] SUP720 IDB Limit

[Stephen Kratzer]

Arie,

We're running at about 75% of the IDB limit on the 7200s, but I believe we're 
suffering from an IOS bug affecting the reclaiming of IDBs for virtual 
interfaces. In the absence of this bug or behavior, IDB limits shouldn't be a 
limiting factor.

What kind of hardware module limitations might bite us? We're just growing 
beyond the OC-3 level (ATM side) and looking to move up to an OC-12.
