Cisco ONS 15454 SDH Installation and Operations Guide, R3.3
May 2002
Chapter 4 IP Networking
Before You Begin
4.1 Before You Begin
Determine how your network will be connected. There are many different ONS 15454 SDH connection
options within an IP environment:
ONS 15454 SDHs can be connected to LANs directly or through a router.
IP Subnetting can create ONS 15454 SDH node groups, allowing you to provision non-DCC
connected nodes in a network.
Different IP functions and protocols can be used to achieve specific network goals. For example,
Proxy Address Resolution Protocol (ARP) enables one LAN-connected ONS 15454 SDH to serve
as a gateway for ONS 15454 SDHs that are not connected to the LAN.
You can create static routes to enable connections among multiple CTC sessions with ONS 15454
SDHs that reside on the same subnet but have different destination IP addresses.
If ONS 15454 SDHs are connected to OSPF networks, ONS 15454 SDH network information is
automatically communicated across multiple LANs and WANs.
ONS 15454 SDH IP addressing generally has eight common scenarios or configurations. Use the
scenarios as building blocks for more complex network configurations.
Table 4-3 provides a general list of items to check when setting up ONS 15454 SDHs in IP networks.
Additional procedures for troubleshooting Ethernet connections and IP networks are provided in
Chapter 9, Ethernet Operation.
