ASR9000 IOS XR 4.2.3 General Release Recommendation
Cisco valued customers seeking to deploy a new ASR9K platform or upgrade from existing IOS-XR
4.1.x/4.2.0/4.2.1/4.2.2 release, should use hardened release IOS-XR 4.2.3 with the following SMUs.
Customers running IOS-XR 3.9.x and 4.0.x should immediately plan upgrade to IOS-XR 4.2.3 upon
certification, as both these releases have reached end of engineering support.
Customers should consider IOS XR 4.3.x, IOS XR 5.1.x for ASR9K deployment and upgrade upon
certification, if needed due to feature availability.
In summary this is the list of Mandatory and Optional SMU's that should be used while deploying 4.2.3.
1) A9K-RSP440 Platform
2) A9K-RSP-4G Platform
1. Recommendation for A9K-RSP440 Platform.

It’s recommended that Reload SMUs are installed together in one install operation; this results in a
single reload vs multiple reloads if the SMUs are installed individually and they are reload type. This is an
example of how to install SMUs together in one install operation, the result is a single reload:
Step 1) install add
A9K-PE3(admin)#install add source tftp://10.10.10.1/ asr9k-p-4.2.3.CSCud37351.pie asr9k-p4.2.3.CSCud54093.pie asr9k-p-4.2.3.CSCuc23551.pie asr9k-p-4.2.3.CSCud19188.pie
Step 2) Install activate
