Zone Configuration
A zone can be configured within the router context or under the base router and/or within the 
IES or VPRN service context. A zone is configured by adding at least one Layer 3 interface 
to the zone configuration. Multiple zones can be created within each service or within the 
router context. Layer 3 interfaces from different services cannot be grouped into a single 
common zone.
