Hi,

What are the magic incantations for netconf for XR? I have lots of experience
with junos, but XR is still a mystery to me :)
Cheers,

Hi,
What is the best/most efficient/most convenient way to push large prefix lists
or sets to an XR router for BGP prefix filtering? Pushing thousands of lines
through the CLI seems foolish, I tried using the load command but it seems
horribly slow. What am I missing? :)
Cheers!

Interesting, but why would 'sh run' or 'write' raise an interrupt?
Isn't this a branch in code that handles the CLI?
this was monolithic IOS running on older platforms. On a non-preemptive
multitasking operating system like this,

Marcin,
I did some benchmarking back in ~2008-2009 (with 12.2.31SB and 12.2SR,
who still remembers that?), and we (Cisco) fixed numerous non optimized
paths in the routing code. But that was over a decade ago, so I’ll
limit bragging about it ;) There are two presentations, quoted from
about that

Yes, but why would XR advertise 1240 if I'm using 'tcp mss 8936' for that

Maybe to access NVRAM? I don't know for sure, I didn't pursue it, I
just know I could observe it.
