Release Information

Statement introduced before JUNOS Release 7.4.

Description

Logical link-layer encapsulation type.

Options

atm-ccc-cell-relay—Use Asynchronous Transfer Mode (ATM) cell relay encapsulation.

atm-ccc-vc-mux—Use ATM VC multiplex encapsulation on circuit cross-connect (CCC) circuits. When you use this encapsulation type, you can configure the family ccc only.

atm-cisco-nlpid—Use Cisco ATM Network Layer Protocol identifier (NLPID) encapsulation. When you use this encapsulation type, you can configure the family inet only.

atm-mlppp-llc—For ATM2 intelligent queuing (IQ) interfaces only, use Multilink Point-to-Point (MLPPP) over ATM adaptation layer 5 (AAL5) logical link control (LLC). For this encapsulation type, your routing platform must be equipped with a Link Services or Voice Services Physical Interface Card (PIC).

atm-nlpid—Use ATM NLPID encapsulation. When you use this encapsulation type, you can configure the family inet only.

atm-ppp-llc—For ATM2 IQ interfaces only, use Point-to-Point Protocol (PPP) over AAL5 logical link control (LLC) encapsulation.

atm-ppp-vc-mux—For ATM2 IQ interfaces only, use PPP over AAL5 multiplex encapsulation.

atm-snap—Use ATM Subnetwork Access Protocol (SNAP) encapsulation.

atm-tcc-snap—Use ATM SNAP encapsulation on translational cross-connect (TCC) circuits.

atm-tcc-vc-mux—Use ATM VC multiplex encapsulation on TCC circuits. When you use this encapsulation type, you can configure the family tcc only.

atm-vc-mux—Use ATM VC multiplex encapsulation. When you use this encapsulation type, you can configure the family inet only.

ether-over-atm-llc—For interfaces that carry IP version 4 (IPv4) traffic, use Ethernet 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 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.

ethernet—Use Ethernet II encapsulation (as described in RFC 894, A Standard For The Transmission Of IP Datagrams Over Ethernet Networks).

frame-relay-ccc—Use Frame Relay encapsulation on CCC circuits. When you use this encapsulation type, you can configure the family ccc only.

frame-relay-ppp—Use Frame Relay encapsulation on PPP circuits.

frame-relay-tcc—Use Frame Relay encapsulation on TCC circuits for connecting unlike media. When you use this encapsulation type, you can configure the family tcc only.

multilink-frame-relay-end-to-end—Use Multilink Frame Relay (MLFR) FRF.15 encapsulation. This encapsulation is used only on multilink, link services, and voice services interfaces and their constituent T1 or E1 interfaces.

multilink-ppp—Use MLPPP encapsulation. This encapsulation is used only on multilink, link services, and voice services interfaces and their constituent T1 or E1 interfaces.

ppp-over-ether—For underlying Ethernet interfaces on Juniper Networks J Series Services Routers only, use PPP over Ethernet encapsulation. When you use this encapsulation type, you cannot configure the interface address. Instead you configure the interface address on the PPP interface. For more information, see the JUNOS Software Interfaces and Routing Configuration Guide.

ppp-over-ether-over-atm-llc—For underlying ATM interfaces on J Series Services Routers only, use PPP over Ethernet over ATM LLC encapsulation. When you use this encapsulation type, you cannot configure the interface address. Instead you configure the interface address on the PPP interface. For more information, see the JUNOS Software Interfaces and Routing Configuration Guide.

vlan-ccc—Use Ethernet virtual LAN (VLAN) encapsulation on CCC circuits. When you use this encapsulation type, you can configure the family ccc only.

vlan-tcc—Use Ethernet VLAN encapsulation on TCC circuits. When you use this encapsulation type, you can configure the family tcc only.

vlan-vpls—Use Ethernet VLAN encapsulation on virtual private LAN service (VPLS) circuits.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
