What is the equivalent of "copy run start" in IOS-XR?

The answer to that question is "none".  Cisco has been saying they're are going to do away with the old command "write" in favour of the LONGER and, sometimes confusing" "copy running-config startup-config" for years.  The decision makers started implementing this with the advent of the Linux-based systems like the IOS-XE & IOS-XR.  

This decision is non-negotiable.  This means one can huff-and-puff-until-blue and the decision will not be reversed. 

A lot of end-users have found the decision "annoying" and have implemented a workaround by creating an alias.

Thanks Leo,

So my question now is, what command do I use on IOS-XR to save running config to nvram or whatever equivalent so the router reboots and loads the saved config once it is back?

Thanks in advance

To save the config?  Use the Cisco recommended command of "copy run start".  Alternatively, one can create a "write" alias.

[danielseijas3010]

But the "copy run start" command is not available on IOS-XR, that was the main reason of my question

[Leo Laohoo]

Please post the complete output to the command "copy ?".

Nevermind I just got confused while working. Thanks everyone

I think the answer you want is the "commit" command. In IOS-XR the configuration is saved across the route processors once you issue the commit command. See the commit help when you are in configuration mode.

Indeed, you can still use the copy command and "running-config" is one of the sources but its destination is not for saving as a startup. It's just to back it up.

RP/0/RP0:IOS_XR9(config)#commit ?
  best-effort   Commit the configuration changes via best-effort operation
  comment       Assign a comment to this commit
  confirmed     Rollback this commit unless there is a confirming commit
  force         Override the memory checks
  label         Assign a label to this commit
  replace       Replace the contents of running configuration
  save-running  Save running configuration to a file
  show-error    Displays commit failures immediately
  <cr>          Commit the configuration changes via pseudo-atomic operation

and here are the copy commands

RP/0/RP0:IOS_XR9#copy running-config ?
  WORD       Copy to file
  config:    Copy to config: file system
  disk0:     Copy to disk0: file system
  disk1:     Copy to disk1: file system
  ftp:       Copy to ftp: file system
  harddisk:  Copy to harddisk: file system
  http:      Copy to http: file system
  https:     Copy to https: file system
  rootfs:    Copy to rootfs: file system
  tftp:      Copy to tftp: file system

...yes, I know this is an old post, but it might help others in the future.
