[c-nsp] Fallback (vlan) Bridging on the 6500

[Michael Kaegler]

I need to run vlan bridging on a 6500 sup2 for 3 weeks. I'm following 
the documentation here: 
http://www.cisco.com/en/US/tech/tk389/tk621/technologies_tech_note09186a00800a7af6.shtml#sample2

"show bridge" tells me, among other things, "Total of 300 station 
blocks, 298 free" (just doing a test vlan right now). Which means I 
have a bridge table of 300 entries, and when I run out, more RAM will 
be allocated for another 300.

Question is, how much RAM and how do I keep track?
I have 1000 entries in the ARP table (95% will be on a bridge at one 
point or another), and roughly 55MB on the router. Am I in store for 
a bad day?

Some output below.
TIA!
