Cisco SD-WAN prefix list

[RS19]

In Cisco SD-WAN, I have prefix list say abc_range : 10.100.0.0/16
This prefix list is used by many localized policy and also centralized policy.

Now I want to add another segment to the prefix list say 10.200.0.0/16 to abc_range

My question is can I add directly to the prefix-list abc_range the new segment or should i detach all the policies, update the prefix-list & then re-attach the policies.

It's fine to add it directly to the existing prefix list

Hi @RS19 ,

Yes, you can directly add 10.200.0.0/16 to the existing prefix-list abc_range without detaching any centralized or localized policies.

Prefix-lists in Cisco SD-WAN are dynamically referenced, so once updated, all associated policies will automatically reflect the change. No need to re-attach or redeploy policies unless the structure itself is modified.

Just ensure you commit and push the updated configuration via vManage.

Hope this helps!
