Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X User Manual

Configuring Ethernet Interfaces
Ethernet interfaces support IP, PPPoE, multinetting (multiple IP addresses), and
VLANs (subinterfaces). Ethernet modules use the Address Resolution Protocol (ARP)
to obtain MAC addresses for outgoing Ethernet frames and support quality of service
(QoS) classification. See JUNOSe Physical Layer Configuration Guide, for a description
of limitations of individual modules.
Use the Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet commands described
in JUNOSe Physical Layer Configuration Guide to:
■ Configure with IP only, with PPPoE only, with both IP and PPPoE, and with or
without VLANs.
■ Specify the line speed and duplex mode.
■ Specify the MTU.
The following sample command sequence configures an IP interface on a VLAN on
an Ethernet interface:
host1(config)#interface fastEthernet 2/0
host1(config-if)#encapsulation vlan
host1(config-if)#interface fastEthernet 2/0.1
host1(config-if)#vlan id 201
host1(config-if)#ip address 192.168.129.5 255.255.255.0
The following sample command sequence adds an IP interface over PPPoE to the
same VLAN:
host1(config)#interface fastEthernet 2/0.1.2
host1(config-if)#encapsulation pppoe
host1(config-if)#interface fastEthernet 2/0.1.2.1
host1(config-if)#encapsulation ppp
host1(config-if)#ip address 192.2.2.1 255.255.255.0
Configuring IPSec-Service Interfaces
IPSec Service modules support interfaces associated with secure IP tunnels. You
configure and delete these interfaces statically; however, the router assigns tunnels
to the interfaces dynamically. This mechanism means that you must manage the
interfaces for tunnels manually; however, the router will add and remove tunnels
when required.
For information about configuring secure IP interfaces, see JUNOSe IP Services
Configuration Guide . For information about managing IPSec service interfaces, see
JUNOSe Physical Layer Configuration Guide.
Configuring Tunnel Service Interfaces
You can configure both dynamic tunnels associated with L2TP and static IP tunnels
on your E Series router; however, you must first install a Service Module (SM).
Dynamic tunnels, which are not associated with a particular interface, are described
