Service Provider Environment - Nortel Contivity 1010 Manual

Table 2 shows how offices with approximately 50 workstations can each have
subnets assigned.

Service provider environment

Service providers generally have an isolated NOC from which all devices are
managed. The addressing scheme could be different from a central office and
require a separate designated tunnel to configure the Contivity 1010, 1050, and
1100.
Every Contivity 1010, 1050, and 1100 must have a distinct IP address that is
visible from the NOC subnet. A NOC can assign any address reachable from a
NOC network to Contivity 1010, 1050, and 1100 devices. BOQS configures NAT
on the NOC tunnel to translate the address specified in the "Branch office switch
manage NAT IP address" and "management address from branch office private
subnet". If the field is empty, the NOC must use an actual management address to
access the Contivity 1010, 1050, or 1100.
Because the NOC tunnel uses static routing, all Contivity 1010, 1050, and 1100
devices must be configured with a static route to the NOC private network. The
NOC private address and NOC private mask fields are where BOQS user enters
this information. This information is the same for all Contivity 1010, 1050, and
1100 devices.
You must provision the NOC switch to accept control tunnel connections from the
branch office. Because static routing is used in control tunnels, you do not have to
enable routing protocols on the NOC switch. Use the following guidelines:
Contivity 1010/ Contivity 1010/1050/
1050/1100 Private 1100 Management
