One problem that we have had with attempting to run Max's in their on stub areas is that they wont incorporate routes external such as routes fed in by radius, Those are treated as external routes and are not advertised. Maybe this can be fixed by implementing NSSA's?

The I960 just isn't the most robust chip on the market. But then again I don't believe the Max was desgined to be a full ABR. I think that the MAXen just get's so many LSAs that > it starts re-running the SPF algorithm so many time that it just eats up > processor and memmory and then just dies. That in conjunction with doing all call setup's , 3 Pri's worth of traffic, and doing simple caculations of the LSA's it's gotta tax the CPU somewhat. Now with the offload of moving the ppp setup down to the DSP's on the digital modem's cards, Those boxes are a lot less taxes, As you will see in the improved throughput with 56K cards.

NOPE. But, I have heard rumors that maybe soon this will be able on the TNT. Kevin can you confirm this?
