Overlapping IP Address Pool Support
Overlapping IP Address Pools provides a mechanism for allowing operators to more flexibly support multiple corporate
VPN customers with the same private IP address space without the expensive investments in physically separate routers,
or expensive configurations using virtual routers.

Routing Protocol Support
The system's support for various routing protocols and routing mechanism provides an efficient mechanism for ensuring
the delivery of subscriber data packets.
the delivery of subscriber data packets.
Description
The following routing mechanisms and protocols are supported by the system:
Static Routes: The system supports the configuration of static network routes on a per context basis. Network
routes are defined by specifying an IP address and mask for the route, the name of the interface in the currant
context that the route must use, and a next hop IP address.
context that the route must use, and a next hop IP address.
Open Shortest Path First (OSPF) Protocol version 2: A link-state routing protocol, OSPF is an Interior
Gateway Protocol (IGP) that routes IP packets based solely on the destination IP address found in the IP packet
header using the shortest path first. IP packets are routed ―as is‖, meaning they are not encapsulated in any
further protocol headers as they transit the network.

Variable length subnetting, areas, and redistribution into and out of OSPF are supported.
OSPF routing is supported in accordance with the following standards:
RFC-1850, OSPF Version 2 Management Information Base, November 1995
RFC-2328, OSPF Version 2, April 1998
RFC-3101 OSPF-NSSA Option, January 2003
