Juniper ACX2000 Configuration Guide

For 8-port, 12-port, and 48-port Fast Ethernet PICs, TCC is not supported.
•
VLAN CCC (vlan-ccc)—Ethernet interfaces with VLAN tagging enabled can use VLAN
CCC encapsulation. VLAN CCC encapsulation supports TPID 0x8100 only. When you
use this encapsulation type, you can configure the ccc family only.
•
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)—Extended VLAN CCC encapsulation supports
TPIDs 0x8100, 0x9100, and 0x9901. When you use this encapsulation type, you can
configure the ccc family only.
•
TCC version (extended-vlan-tcc)—Similar to CCC, but used for circuits with 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.
NOTE: In ACX Series routers, VPLS is supported only on ACX5048 and
ACX5096 routers.
•
Ethernet VPLS (ethernet-vpls)—Ethernet interfaces with VPLS enabled can use
Ethernet VPLS encapsulation. For more information about VPLS, see the Junos OS
VPNs Library for Routing Devices.
•
Ethernet VLAN VPLS (vlan-vpls)—Ethernet interfaces with VLAN tagging and VPLS
enabled can use Ethernet VLAN VPLS encapsulation. For more information about
VPLS, see the Junos OS VPNs Library for Routing Devices.
•
Extended VLAN VPLS (extended-vlan-vpls)—Ethernet interfaces with VLAN 802.1Q
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 OS VPNs Library
for Routing Devices.
•
Flexible Ethernet services (flexible-ethernet-services)—Gigabit Ethernet and Gigabit
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 Ethernet services encapsulation on
