without VLANs. Using subscriber interfaces, the router can demultiplex or separate
the traffic associated with different subscribers.
You can configure subscriber interfaces with VLANs. If you do so, the E Series router
demultiplexes packets by using first the VLAN and then the subscriber interface.
Moving Interfaces
A shared IP interface that has associated subscriber demultiplexing attributes retains
these attributes when it moves.
For details about moving shared IP interfaces, see the
Moving IP Interfaces
section
in
JUNOSe IP, IPv6, and IGP Configuration Guide
.
Preventing IP Spoofing
You can prevent IP spoofing on subscriber interfaces by using media access control
(MAC) address validation.
For information about configuring MAC address validation, see the
MAC Address
Validation
section in
JUNOSe IP, IPv6, and IGP Configuration Guide
.
For information about the relationship between the MAC address validation state
and dynamically created subscriber interfaces, see “Inheritance of MAC Address
Validation State for Dynamic Subscriber Interfaces” on page 607.
Routing Protocols
You configure unicast routing protocols on subscriber interfaces in the same way
that you configure routing protocols on primary IP interfaces, provided that you
configure them to use unicast addressing when communicating with a peer. You can
also enable multicast routing protocols such as IGMP on subscriber interfaces;
however, we do not recommend this type of configuration.
Policies and QoS
You can configure policies, such as rate limiting and filtering, and quality of service
(QoS) for subscriber interfaces in the same way that you do for primary IP interfaces.
For more information, see the
JUNOSe Policy Management Configuration Guide
and
the
JUNOSe Quality of Service Configuration Guide
.
Applications
In a cable modem network, service providers can use subscriber interfaces to:
■
Direct traffic toward special local content in the network
■
Differentiate traffic for virtual private networks (VPNs)
