E Series routers support dynamic interfaces on two types of static interfaces: ATM and
VLAN. This chapter provides configuration information for ATM and then for VLANs.
E Series routers support dynamic ATM 1483 subinterfaces over static ATM interfaces.
E Series routers support the following types of dynamic interfaces over VLAN major
interfaces:
Dynamic VLAN subinterface over static VLAN major interface
IP over dynamic VLAN subinterface
IP over PPPoE over dynamic VLAN subinterface
Internet Protocol version 4 (IPv4) is supported for all bulk-configured dynamic interface
columns over dynamic ATM 1483 subinterfaces and over dynamic VLAN subinterfaces.
Currently, Internet Protocol version 6 (IPv6) is supported only when PPP or MLPPP is
the layer immediately below the IPv6 layer in the interface column. IPv6 is not supported
directly over dynamic ATM 1483, dynamic bridged Ethernet, or dynamic VLANs.
Bulk-configured dynamic interface columns that support IPv6 include the following:
Dynamic IPv6 over dynamic PPP over dynamic ATM 1483
Dynamic IPv6 over dynamic MLPPP over dynamic ATM 1483
Dynamic IPv6 over dynamic PPP over dynamic PPPoE over dynamic ATM 1483
Dynamic IPv6 over dynamic MLPPP over dynamic PPPoE over dynamic ATM 1483
Dynamic IPv6 over dynamic PPP over dynamic PPPoE over dynamic VLAN
Dynamic IPv6 over dynamic MLPPP over dynamic PPPoE over dynamic VLAN
For more information about IPv4, see chapter Configuring IP in JunosE IP, IPv6, and IGP
Configuration Guide. For more information about IPv6, see chapter Configuring IPv6 in
JunosE IP, IPv6, and IGP Configuration Guide.
You can use profiles to configure dynamic interfaces over ATM and VLAN interfaces. A
profile is a set of characteristics that can be dynamically assigned to interfaces. By using
a profile, you reduce the management of a large number of interfaces by applying a set
of characteristics to multiple interfaces.
When you are configuring a large number of interfaces with the same attributes at the
higher layers, you can use a profile to factor out all the common attributes of each layer
into one place. This action affects one or more dynamic layers of the interface column.
After you define the static lower layers, you assign a profile to the highest static layer of
the interface column.
When a dynamic interface is configured, the configuration data received from the RADIUS
authentication server typically overrides configuration data obtained from a profile.
