Configuring Interface Encapsulation on Physical Interfaces
address match, the packet is encapsulated with an LLC/SNAP and media access
control (MAC) header, and the packet is forwarded to the ATM interface.
Ethernet cross-connect—Ethernet interfaces without VLAN tagging can use
Ethernet CCC encapsulation. Two related versions are supported:
CCC version (
ethernet-ccc
ID (TPID) tagging can use Ethernet CCC encapsulation. When you use this
encapsulation type, you can configure the
TCC version ( ethernet-tcc
media on either side of the connection.
For 8-port, 12-port, and 48-port Fast Ethernet PICs, TCC is not supported.
VLAN CCC ( )—Ethernet interfaces with VLAN tagging enabled can use
vlan-ccc
VLAN CCC encapsulation. VLAN CCC encapsulation supports TPID 0x8100 only.
When you use this encapsulation type, you can configure the
Extended VLAN cross-connect—Gigabit Ethernet interfaces with VLAN 802.1Q
tagging enabled can use extended VLAN cross-connect encapsulation. (Ethernet
interfaces with standard TPID tagging can use VLAN CCC encapsulation.) Two
related versions of extended VLAN cross-connect are supported:
CCC version (
extended-vlan-ccc
TPIDs 0x8100, 0x9100, and 0x9901. When you use this encapsulation type,
you can configure the
TCC version (
extended-vlan-tcc
different media on either side of the connection.
For 8-port, 12-port, and 48-port Fast Ethernet PICs, extended VLAN CCC is
not supported. For 4-port Gigabit Ethernet PICs, extended VLAN CCC and
extended VLAN TCC are not supported.
Ethernet VPLS ( ethernet-vpls
Ethernet VPLS encapsulation. For more information about VPLS, see the JUNOS
VPNs Configuration Guide and the JUNOS Feature Guide.
Ethernet VLAN VPLS (
vlan-vpls
enabled can use Ethernet VLAN VPLS encapsulation. For more information about
VPLS, see the JUNOS VPNs Configuration Guide and the JUNOS Feature Guide.
Extended VLAN VPLS ( extended-vlan-vpls
tagging and VPLS enabled can use Ethernet Extended VLAN VPLS encapsulation.
(Ethernet interfaces with standard TPID tagging can use Ethernet VLAN VPLS
encapsulation.) Extended Ethernet VLAN VPLS encapsulation supports TPIDs
0x8100, 0x9100, and 0x9901. For more information about VPLS, see the JUNOS
VPNs Configuration Guide and the JUNOS Feature Guide.
Flexible Ethernet services (
Ethernet IQ and IQE PICs with SFPs (except the 10-port Gigabit Ethernet PIC and
the built-in Gigabit Ethernet port on the M7i router) can use flexible Ethernet
services encapsulation. Aggregated Ethernet bundles can use this encapsulation
type. You use this encapsulation type when you want to configure multiple
per-unit Ethernet encapsulations. This encapsulation type allows you to configure
any combination of route, TCC, CCC, Layer 2 virtual private networks (VPNs),
and VPLS encapsulations on a single physical port. If you configure flexible
