With JUNOS software, you can partition a single physical system into multiple logical systems that perform independent routing tasks. Each logical system has its own unique routing tables, interfaces, policies, and routing instances. A set of logical systems within a single router can handle the functions otherwise performed by several small routers, offering an effective way to maximize the use of a single routing or switching platform.

Note: A virtual router does not have the same capabilities as a logical system. A virtual router is a type of simplified routing instance that has a single routing table. By contrast, a logical system is a partition of the main router and can contain multiple virtual router routing instances. As a result, these two entities are not equivalent. |
