Except that some times, it did lead to crash (for us=20
anyway), because it eats up half the router's memory, and if=20
you're running 3x full tables or more, you ran out of the=20
other half and BOOM! And that was IOS XR 2, which is=20
generally old now.

We now turn off software redundancy now on all ASR1000 boxes=20
that don't have a 2nd RP.
