Virtual Router Configuration
Virtual routing enables you to partition virtual domains within the global IP router.
Each virtual domain is defined by a named virtual router. Currently, the Stinger
IP2000 controller supports up to 1022 virtual routers in addition to the global router.
If you do not configure virtual routers, the global IP router operates as documented
in Chapter 4, “IP Router Configuration.” All interfaces that are not explicitly grouped
with a defined virtual router are grouped with the global router.
Overview of virtual routing
Virtual routing enables high-density circuit termination with secure logical
partitioning and multiple route tables. Virtual routing is particularly useful for remote
access server (RAS) functionality. For example, it can securely partition traffic from
many CPE devices to different ISPs, with each ISP mapped to a separate virtual
domain. Figure 5-1 shows a simplified diagram with three virtual routers configured
in the global router. Because each virtual router has its own routing table, traffic
within a virtual domain is typically not shared with other domains.
