• Modification of the frame header at R2
[2.3.3 Martini] – The 4-byte VLAN tag is transported as is, and MAY be
overwritten by the egress router.
DOES NOT COMPLY – The VLAN tag will not be modified by egress R2
switch.
General Configuration Guidelines for L2MPLS
1. Configure ECN330-switch to L2MPLS mode (“Configuring the ECN330-
switch for Normal Operation or Tunneling Mode” on page 71).
2. Create a normal VLAN (“Creating VLANs” on page 284).
3. Enable L2MPLS mode in the VLAN interface (L2MPLS VLAN Binding –
VLAN Mode, section 6.13.1 on page 319).
4. Associate L2MPLS VLAN to a Virtual Channel, specifying the MPLS input
and output labels (MPLS VLAN Binding – Input Label and Output Label,
section 6.13.1 on page 319).
5. Configure a Gigabit Ethernet port to L2MPLS uplink mode (L2MPLS Port
Configuration – Status, section 6.13.2 on page 320).
6. Specify the tunnel label, virtual channel (VC), next hop, and maximum
transfer unit (MTU) used by the uplink port (L2MPLS Port Configuration –
Tunnel Label, VC Label, Next-Hop, and MTU, section 6.13.2 on page 320).
Note that the MTU for the uplink port must be bigger than 1544 bytes.
6.13.1 Binding a VLAN to an MPLS Tunnel
Use the L2MPLS VLAN Configuration page to configure a VLAN to operate as
an L2MPLS tunnel, and associate the MPLS input and output labels with the
VLAN.
Command Attributes
• VLAN – ID of configured VLAN. (Default: 1, Range: 1-4094)
• VLAN Mode – Configures a VLAN to operate in normal IEEE 802.1Q
mode or to operate as an L2MPLS tunnel. (Default: Normal Mode)
• Input Label (0-1048574) – MPLS input label. (Range: 0-1048574)
• Output Label (0-1048574) – MPLS output label. (Range: 0-1048574)
