Building A Management Network; A.1 - Preliminary Remark; A.1.1 - Unique Address; A.1.2 - Supervision Of Ppp Link - Sagem ADR 155C Guide D'installation Et D'utilisation

This appendix provides a brief description of the rules governing construction of a
telecommunications management network based on the IP protocol stack.

A.1 - Preliminary remark

The ADR155c management network is based on the IP protocol stack. Each network node
(each ADR155c) integrates an IP router which routes each packet to its destination; these
network nodes are connected together by PPP ( Point to Point protocol) link.

A.1.1 - Unique address

Each ADR has an IP address called an "equipment address" (based on release P3.1). This
address must be configured when the ADR is commissioned. This is the only IP address used
by the management system. The ADR must be declared with this address in the manager. All
information (alarms, events) concerning the ADR are then notified to the manager with the
equipment address.

A.1.2 - Supervision of PPP link

The PPP links (whatever their physical support: DCCr, DCCm, VC12, MNGT..) are supervised.

A.1.3 - Routing protocols

The ADR155c has two routing protocols, RIP and OSPF (available as of P3.1)
The RIP protocol is limited to 16 "hops" in the network. The OSPF protocol enables
management of large sized networks. The OSPF protocol does not require any special
configuration; it is always necessary to ensure that all the network elements are in the same
"area".
A.1.4 - Unnumbered links
When creating a PPP link, the operator has two choices: either the link is numbered or it is
unnumbered. This is independent of the protocol selected (RIP or OSPF). The unnumbered
links do not have an IP address and therefore more easily enable construction of a network
(since there is no need to define all the IP addresses of all the links).

A.2 - Construction of an IP network

Functionally, there are two types of routes: static and dynamic.

A.2.1 - Static routes

In the ADR155c, the static routes are used to configure routes which are not learned by the
routing protocols and located "on the periphery" of the protocol areas or domains: routes to
machines on Ethernet network such as manager, for example.
