XR 4.2.1 Issue with stale routes

[cisco-reseller]

I have an issue with stale route which can only be resolved by using the command 'clear route ipv4 unicast <prefix>'

We have been running this IOS verision for a while and this is the first time that we have seen this.

Anyone seen this issue before?

Yes known issue in 421 I have seen that before.

There is not enough detail obviously in this request to pinpoint to the exact DDTS/smu that you are running into, but I want to make 2 recommendations here:

either apply the latest smu's for 421 (use Cisco Software Manager/CSM) to help with the SMU mgmt as I realize that is a PHD task on its own, or consider 423 with its latest smu's.
