To commit a configuration on both Routing Engines at a specified time in the future, the application encloses the <synchronize/> and <at-time> tag elements in <commit-configuration> and <rpc> tag elements:
<rpc>
<commit-configuration>
<synchronize/>
<at-time>time</at-time>
</commit-configuration>
</rpc>
<rpc>
<commit-configuration>
<force-synchronize/>
<at-time>time</at-time>
</commit-configuration>
</rpc>
As when the <at-time> tag element is emitted by itself, the JUNOScript server verifies syntactic correctness immediately and does not emit additional tag elements when it actually performs the commit operation on each Routing Engine. For information about how to specify the time in the <at-time> tag element, see Committing the Candidate Configuration Only After Confirmation.
