Configuring IP Router Parameters
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.
