Optical Networking Systems (ONS) is a group of optical products from Cisco providing backbone transport, metro access, and wavelength division services. Effective management of these ONS devices requires careful planning and design and clear understanding of the characteristics of the devices and the tools and options that are available.
ONS IP management is a complex subject with little information available beyond the basic configuration. This Short Cut was created based on real customer needs from years of supporting ONS customers and providing expert-level consulting services.
Optical Networking Systems IP Management Solutions goes well beyond the basic documentation and focuses on practical network support needs while also providing guidelines for strategic design and planning requirements. A variety of topics are covered, from the basic configurations to in-depth design solutions. This Short Cut helps you with IP setup and configuration, problem troubleshooting, architectural migration, and planning and design.

- 1. Introduction
-
2. Node Addressing Schemes
- Basic IP Addressing and Forwarding Rules
- A Common Addressing Scheme
- GNE Addressing Rules
-
ENE Addressing Rules
- Rule 1: All Static ENEs Can Be on the Same Subnet as the NOC-bound GNEs That Are Reachable over DCC
- Rule 2: For Optimal Forwarding, ENEs Should Be on Subnets Separate from NOC-bound GNEs
- Rule 3: For Proper Address Summarization, ENE Subnets Should Be Assigned in a Contiguous Fashion to Use Adjacent Subnets
- Rule 4: ENE Subnets Should Not Cross OSPF Area Boundaries

3. Proxy ARP and ARP Sniffing
- Address Resolution Protocol
-
Proxy ARP
- Rule 1: A PAS Responds Only to ARP Requests from the LAN for Peer Addresses on the Same Subnet as the GNE
- Rule 2: Peers Must Be Reachable by the PAS GNE via a Host Route
- Rule 3: Peers Must Be on the Same OSPF Area as the PAS GNE, or Share One Common Area if the PAS GNE Is on More Than One Area
- Rule 4: A PAS GNE Does Not Perform PAS for LAN Peers Attached to the Local LAN of the GNE
- Rule 5: Fragmented LAN Peers May Become PAS Clients
- Rule 6: On a Given LAN Segment, All GNEs Sharing the Same OSPF Database Compete for PAS. Only the One with the Highest MAC Address Becomes the PAS, and All Other GNEs Become PAS Candidates
- ARP Sniffing
- Review Questions
- 4. Static Routing
-
5. Dynamic Routing
- OSPF Routing on ONS
- OSPF Area Design
- Inter-Area Address Summarization
-
OSPF Deployment Tips
- Tip 1: Ensure Redundant Area 0 and Inter-area Connections
- Tip 2: Plan Area IDs to Avoid Migration
- Tip 3: Ensure That OSPF Is Properly Configured on the Routers Attached to the LAN Before OSPF Is Enabled on GNE ABRs
- Tip 4: Balance Summarization with Forwarding Optimization
- Tip 5: Limit Total OSPF Entries in the Routing Table to Fewer Than 700
- Tip 6: Be Conservative When It Comes to Modifying OSPF Default Settings on GNEs
- OSPF Area Migration
- RIP Routing
