Configuring Extended VLAN Encapsulation

[Contents] [Prev] [Next] [Index] [Report an Error]

Gigabit Ethernet, 4-port Fast Ethernet, MX-series router Gigabit Ethernet, Tri-Rate Ethernet copper, 10-Gigabit Ethernet, and aggregated Ethernet interfaces with VLAN tagging enabled can use extended VLAN CCC or VLAN VPLS, which allow 802.1Q tagging. To configure the encapsulation on a physical interface, include the encapsulation statement at the [edit interfaces interface-name] hierarchy level, specifying extended-vlan-ccc or extended-vlan-vpls:



[edit interfaces interface-name]

encapsulation (extended-vlan-ccc |
extended-vlan-vpls);

For extended VLAN CCC and extended VLAN VPLS encapsulation, all VLAN IDs 1 and higher are valid. VLAN ID 0 is reserved for tagging the priority of frames.

Note: For extended VLAN CCC, the VLAN IDs on ingress and egress interfaces must be the same. For back-to-back connections, all VLAN IDs must be the same.

Example: Configuring Extended VLAN Encapsulation on a Gigabit Ethernet Interface

Configure extended VLAN CCC encapsulation on Gigabit Ethernet ingress and egress interfaces:



interfaces ge-0/0/0 {
vlan-tagging;
encapsulation extended-vlan-ccc;


unit 0 {
vlan-id 2;
family ccc;
}


}
interfaces ge-1/0/0 {
vlan-tagging;
encapsulation extended-vlan-ccc;


unit 0 {
vlan-id 2;
family ccc;
}


}

Example: Configuring Extended VLAN Encapsulation on an Aggregated Ethernet Interface

Configure extended VLAN VPLS encapsulation on an aggregated Ethernet interface:



interfaces ae0 {
vlan-tagging;
encapsulation extended-vlan-vpls;


unit 0 {
vlan-id 100;
}


}
