That's good to know. I wonder if there are any limitations whatsoever or
simply a mistake in the documentation and the Hardware Compatibility
Tool).
I could be wrong, but the way I understand it, the original SCB only has 80Gb/s
of fabric capacity. While the 16XGE MPC will technically work, it will only
work at half capacity. For full throughput capability, you would need two SCBs
for a total of 160Gb/s fabric capacity, but if you lose one of the SCBs, you
lose half your capacity. Again, my understanding could be wrong, so someone
please correct me if so.
It is just not worth it to invest in SCB or even SCBE at this point. I'd also
be concerned about the 2GB RE with 3x full route BGP feeds. While it will hold
3x full feeds in RIB, your memory usage will be pretty high (+75-80%) and if
enable something that uses RE memory like sampling, you might as well forget
about having a solid router anymore.
