RFC 4779 ISP IPv6 Deployment Scenarios in BB January 2007
7.6. IPv6 Network Management
The necessary instrumentation (such as MIB modules, NetFlow Records,
etc.) should be available for IPv6.
Usually, NSPs manage the edge routers by SNMP. The SNMP transport
can be done over IPv4 if all managed devices have connectivity over
both IPv4 and IPv6. This would imply the smallest changes to the
existing network management practices and processes. Transport over
IPv6 could also be implemented and it might become necessary if IPv6
only islands are present in the network. The management applications
may be running on hosts belonging to the NSP core network domain.
Network Management Applications should handle IPv6 in a similar
fashion to IPv4; however, they should also support features specific
to IPv6 such as neighbor monitoring.
In some cases, service providers manage equipment located on
customers' LANs.
8. Wireless LAN
This section provides a detailed description of IPv6 deployment and
integration methods in currently deployed wireless LAN (WLAN)
infrastructure.
8.1. WLAN Deployment Scenarios
WLAN enables subscribers to connect to the Internet from various
locations without the restriction of staying indoors. WLAN is
standardized by IEEE 802.11a/b/g.
Figure 8.1 describes the current WLAN architecture.
