64 bit IOS-XR.

What Tom said ^

It's not ideal if you have older RSPs or Triden or Typhoon cards but
yeah migrating to newer RSPs and line cards is the way we are going
and using 64 bit IOS-XR.

Did you mean RSP880-LT? RL is the rate limited version down to 440Gbps
which is license to 880Gbps.

Yeah it isn't great. For new boxes we are deploying 64bit capable RSPs
and Tomahawk cards from the get-go to get the longevity but for older
boxes it's a head scratcher.

We use it in the same way we have been using 32 bit so I can't it's
anything to shout about, i.e. bugs aside it "just works", which is
what I would expect.
