[c-nsp] Most Stable IOS-XR Version for ASR9K

[Xu Hu]

Hi Folks,

Any idea which version is the most stable one currently, need to deploy new
ASR9K inside the network, am considering to use which version.

No need additional features, just normal OSPF, BGP, MPLS, MPLS/TE, MPLS/VPN.

Thanks in advance.
