[Subscriber Access]
Support for PPPoE Layer 3 wholesale configuration in a subscriber access
network Enables you to configure PPPoE Layer 3 wholesaling within a
subscriber access network. Wholesale access is the process by which an access
network provider partitions the access network into separately manageable and
accountable subscriber segments for resale to other network providers. An access
network provider may elect to wholesale all or part of its network to one or more
service providers (retailers).
In a Juniper Networks subscriber access network, you accomplish Layer 3
partitioning through the use of logical systems (LSs) and routing instances. Logical
systems enable you to divide a physical router into separate, distinct, logical
administrative domains. This method of division enables multiple providers to
administer the router simultaneously and each have access to only the portions
of the configuration that are relevant to their specific logical system. The JUNOS
Software supports up to 15 named logical systems in addition to the default
logical system (inet.0).
Routing instances are typically used in Layer 3 VPN scenarios. A routing instance
does not have the same level of administrative separation as does a logical
system. The routing instance defines a distinct routing table, set of routing
policies, and set of interfaces, but it does not provide administrative isolation.
