Comparing Two Previous (Rollback) Configurations

To compare the contents of two previously committed (rollback) configurations, a client
application emits the Junos XML

equivalent to the

option. The <rollback> tag element specifies the index number of the configuration that
is the basis for comparison. The

elements range from (zero, for the most recently committed configuration) through

configuration results in the second configuration, whereas a minus sign means that
removing the statement from the base configuration results in the second configuration.
