Overlapping Networks

Overlapping networks are when two or more private networks with the same addressing schemes terminate on one phy-interface. The problem this creates can easily be solved by using VLAN tagging. For example, two 10.x.x.x networks terminating on one Oracle Communications Session Border Controller network interface will obviously not work. The Oracle Communications Session Border Controller includes the IP Address, Subnet Mask, and 802.1q VLAN tag in its Network Interface determination. This allows Oracle Communications Session Border Controller to directly interface to multiple VPNs with overlapping address space.
