IOS XR possible missing documentation.(and workaround)

[mariokamenjak]

Hello. 1)It seems that scrapli is unable to authenticate to ASR9K running IOS XR v6.8.1.

The workaround is to force the Netmiko driver.

2)The Netmiko driver however does not like the default RSA keys.

The solution to that is to generate ecdsa keys on the router: crypto key generate ecdsa nistp256

Perhaps 1) Netmiko should become the default for cisco_xr. And 2) can someone better than me at Github update the documentation for using Netmiko with IOS xr on hyperglass? :)
