Understanding VPLS VLAN Encapsulation
Gigabit Ethernet IQ, Gigabit Ethernet PIMs with small form-factor pluggable optics (SFPs), SRX Series devices with Gigabit Ethernet, Tri-Rate Ethernet copper, and 10-Gigabit Ethernet interfaces with VLAN tagging enabled can use flexible Ethernet services, VLAN virtual private LAN service (VPLS) encapsulation.
VLAN encapsulation is not supported on SRX100 devices because there is no Gigabit Ethernet port.
Aggregated Ethernet interfaces configured for VPLS can use Ethernet VPLS or VLAN VPLS.
To configure the encapsulation on a Gigabit Ethernet IQ or Gigabit Ethernet physical interface, include the encapsulation statement at the [edit interfaces interface-name] hierarchy level, specifying vlan-ccc or vlan-vpls:
[edit interfaces interface-name] encapsulation (vlan-ccc | vlan-vpls);
To configure the encapsulation on an aggregated Ethernet interface, include the encapsulation statement at the [edit interfaces interface-name] hierarchy level, specifying ethernet-vpls or vlan-vpls:
[edit interfaces interface-name] encapsulation (ethernet-vpls | vlan-vpls);
Ethernet interfaces in VLAN mode can have multiple logical interfaces. In CCC and VPLS modes, VLAN IDs from 1 through 511 are reserved for normal VLANs, and VLAN IDs 512 through 4094 are reserved for CCC or VPLS VLANs. For 4-port Fast Ethernet interfaces, you can use VLAN IDs 512 through 1024 for CCC or VPLS VLANs.
