You need to configure interface ge-0 with an IP address of 172.16.100.1. You have accidentally entered 172.16.101.1 as shown in the exhibit.
Which command should you issue to solve the problem?

Reference / correct answer:
[edit] userOrouter# rollback 0
Because you only ran
commit check (which validates configuration syntax but does not activate/commit the candidate configuration), the incorrect address is still only in the candidate configuration. To discard all uncommitted changes and return the candidate configuration to match the active configuration (the last committed config), use
rollback 0. After that, configure the correct IP address and commit.
