To commit the candidate configuration on both Routing Engines but require confirmation for the commit to become permanent, the application encloses the <synchronize/>, <confirmed/>, and (optionally) <confirm-timeout> tag elements in <commit-configuration> and <rpc> tag elements:
<rpc>
<commit-configuration>
<synchronize/>
<confirmed/>
[<confirm-timeout>minutes</confirm-timeout>]
</commit-configuration>
</rpc>
The same rollback deadline applies to both Routing Engines and can be extended on both at once by again emitting the <synchronize/>, <confirmed/>, and (optionally) <confirm-timeout> tag elements on the Routing Engine where the tag elements were emitted the first time.
The <force-synchronize/> tag cannot be combined with the <confirmed/> and <confirm-timeout> tag elements.
For more information about confirmed commit operations, see Committing the Candidate Configuration Only After Confirmation.
