Method and system for managing multiple overlapping address domains
First Claim
1. A system for managing a network including multiple overlapping private address domains, the system comprising:
- a computer system including software for a network management system; and
a plurality of network address translation (NAT) devices, each NAT device in the plurality being communicatively coupled to said computer system and communicatively coupled to one of the overlapping private address domains, wherein a route distinguisher is associated with each overlapping private address domain to facilitate management thereof.

Abstract
One embodiment disclosed relates to a method of configuring a network including multiple overlapping private address domains. A configuration file is created for each overlapping address domain (OAD). The configuration file includes an identifier for the OAD, a gateway address to the OAD, and mappings between private addresses in the OAD and corresponding management addresses. Another embodiment relates to a system for managing a network including multiple OADs. Another embodiment relates to a method of processing a trap from a network with multiple OADs. Another embodiment relates to a method of finding an active route across a static NAT device.

15. A method of processing a trap from a network with multiple overlapping private address domains, the method comprising:
-
receiving a trap packet originating from a managed network device;
extracting a management internet protocol (IP) address from a header of the trap packet;
determining a domain identifier and a private IP address corresponding to the management IP address; and
using the domain identifier and private IP address to uniquely identify the managed network device. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of finding an active route across a static network address translation (NAT) device, the method comprising:
-
finding a gateway to a private network, wherein the gateway comprises the static NAT device;
looking-up a private address of a next device in the private network;
determining a corresponding management address;
adding the management address to a route being calculated; and
repeating the looking-up, determining, and adding steps until the next device comprises a destination device. - View Dependent Claims (22, 23)

25. An apparatus for processing a trap from a network with multiple overlapping private address domains, the apparatus comprising:
-
means for receiving a trap packet originating from a managed network device;
means for extracting a management internet protocol (IP) address from a header of the trap packet;
means for determining a domain identifier and a private IP address corresponding to the management IP address; and
means for using the domain identifier and private IP address to uniquely identify the managed network device.

26. An apparatus for finding an active route across a static network address translation (NAT) device, the apparatus comprising:
-
means for finding a gateway to a private network, wherein the gateway comprises the static NAT device;
means for looking-up a private address of a next device in the private network;
means for determining a corresponding management address;
means for adding the management address to a route being calculated; and
means for repeating the looking-up, determining, and adding steps until the next device comprises a destination device.
