Flexible CLI Configuration Groups

Flexible command line interface (CLI) configuration groups provide the ability to minimize repetitive
configurations by defining a series of configuration statements in a configuration group, and then applying
this group to multiple hierarchical levels in the router configuration tree.
Flexible CLI configuration groups utilize regular expressions that are checked for a match at multiple submodes
of the configuration tree based on where the group is applied within the hierarchy. If a match is found at a
configuration submode, the corresponding configuration defined in the group is inherited within the matched
submode.
Flexible CLI configuration groups also provide an auto-inheritance feature. Auto-inheritance means that any
change done to a CLI configuration group is automatically applied to the configuration in any matched
submodes that have an apply-group at that hierarchical level. This allows you to make a configuration change
or addition once, and have it applied automatically in multiple locations, depending on where you have applied
the flexible CLI configuration group.
