Are IOS XR upgrades still such a pain today? (We never moved to XR64,
and all I know is ASR9001, where the fastest way to do major upgrades
still is "turbo boot" with 2+ hours of downtime...)
In XR7 there's "install replace" which is relatively simple and fast,
though the .iso images it uses can be quite big (580MB to 2GB depending
on platform). So not as quick as IOS, but quite a bit better than your
experience with earlier IOS-XR versions.
This is one of the nice bits about IOS, IOS XE, EOS, etc. - "upload one
image onto the box, reload, upgrade done" (and on EOS, the flash is
actually fast enough to make the "upload" really use available bandwidth
to the box...)
XR7's install replace can install directly from ftp:// URLs. From what
my teammates say, copying/writing to flash still seems slow though.
The NCS540 (using IOS-XR) actually reboot faster than the ASR920s (IOS-XE).
A step in the right direction, I suppose...
Mark.
