Hi juniper-nsp,

Hi,

We got another MX10003 and we are updating it before get in production.
Reading the 19.4R3 release notes, we noticed that two
features update-threading  and  rib-sharding and I really liked what it
"promises" as faster BGP updates .

But there is a catch. We can't use this new feature with non-stop 
routing
enabled.

The question is , are these features worth the non-stop routing loss?

Regards

That message seems didn't get any response.
However, I found an explanation at the bottom the page: 
https://www.juniper.net/documentation/us/en/software/junos/cli-reference/topics/ref/statement/rib-sharding-edit-protocols-bgp.html
Support for NSR with sharding introduced in Junos OS Release 22.2.
BGP sharding supports IPv4, IPv6, L3VPN and BGP-LU from Junos OS Release 
20.4R1.

Still need to test and confirm on this platform, but on another router 
it already works.
