Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual page 1169

—For interfaces that carry IPv4 traffic, use Ethernet over ATM LLC
ether-over-atm-llc
encapsulation. When you use this encapsulation type, you cannot configure
multipoint interfaces.
ether-vpls-over-atm-llc —For ATM2 IQ interfaces only, use the Ethernet virtual private
LAN service (VPLS) over ATM LLC encapsulation to bridge Ethernet interfaces
and ATM interfaces over a VPLS routing instance (as described in RFC 2684,
Multiprotocol Encapsulation over ATM Adaptation Layer 5). Packets from the ATM
interfaces are converted to standard ENET2/802.3 encapsulated Ethernet frames
with the frame check sequence (FCS) field removed.
ether-vpls-over-fr —For E1, T1, E3, T3, and SONET interfaces only, use the Ethernet
virtual private LAN service (VPLS) over Frame Relay encapsulation to support
Bridged Ethernet over Frame Relay encapsulated TDM interfaces for VPLS
applications, as per RFC 2427 (1490).
—For E1, T1, E3, T3 and SONET interfaces only, use the Ethernet
ether-vpls-over-ppp
virtual private LAN service (VPLS) over point-to-point-protocol (PPP) encapsulation
to support Bridged Ethernet over PPP encapsulated TDM interfaces for VPLS
applications.
ethernet —Use Ethernet II encapsulation (as described in RFC 894, A Standard for the
Transmission of IP Datagrams over Ethernet Networks).
ethernet-vpls —Use Ethernet VPLS encapsulation on Ethernet interfaces that have
VPLS enabled and that must accept packets carrying standard Tag Protocol ID
(TPID) values.
—Use extended virtual LAN (VLAN) VPLS encapsulation on Ethernet
extended-vlan-vpls
interfaces that have VLAN 802.1Q tagging and VPLS enabled and that must
accept packets carrying TPIDs 0x8100, 0x9100, and 0x9901.
NOTE: The built-in Gigabit Ethernet PIC on an M7i router does not support extended
VLAN VPLS encapsulation.
frame-relay-ccc —Use Frame Relay encapsulation on CCC circuits. When you use this
encapsulation type, you can configure the
frame-relay-ppp —Use PPP over Frame Relay circuits. When you use this encapsulation
type, you can configure the
frame-relay-ppp encapsulation.
—Use Frame Relay encapsulation on TCC circuits for connecting unlike
frame-relay-tcc
media. When you use this encapsulation type, you can configure the
only.
—Use Frame Relay ether type encapsulation for compatibility
frame-relay-ether-type
with Cisco Frame Relay. The physical interface must be configured with
flexible-frame-relay encapsulation.
