Configuring VPLS instances
3
Specifying the VPLS VC type
The default VC type for all VPLS instances is set to 0x5 or “Ethernet”. For compatibility with
previous versions, the VC type can be changed to 0xB or “Ethernet VPLS”. The VC type must match
between peers for the VPLS session to be established.
To change the VPLS VC type, use the following command at the MPLS configuration level.
Brocade(config-mpls)# vpls-vc-type-ethernet-vpls
VPLS VC type is 0xB (Ethernet VPLS) after the user saves to config and reboots.
Syntax: [no] vpls-vc-type-ethernet-vpls
The default is raw mode.
Configuration Considerations
• When the VPLS instance is configured with the raw pass through mode, all of its local
endpoints must be either all untagged or all tagged. No intermix of modes is allowed.
• Whenever the VC mode configuration changes, whether it is from raw to raw pass through or
vice versa, the VC for all the peers is torn down and then re-binds even though the actual
VC-Type remains the same.
Configuring VPLS raw pass through mode
This section describes how to enable, disable, and view the configuration details of VPLS raw pass
through mode.
Enabling VPLS raw pass through mode
To enable VPLS raw pass through mode, the user must first create the VPLS instance. When the
VPLS instance does not already exist, then enter commands such as the following at the MPLS
VPLS configuration level of the CLI.
Brocade(config-mpls)# vpls test 100
Brocade(config-mpls-vpls-test)# vc-mode raw-pass-through
Syntax: [no] vc-mode raw-pass-through
When the VPLS instance already has mixed endpoints configured, or the VC mode is already
configured as raw pass through and an attempt to add a different type of endpoint then what it
already contains, the following error message is displayed.
“Error: All endpoints under raw-pass-through must be all untagged or all tagged.”
Disabling VPLS raw-pass-through mode
Except for VPLS instances on which ISID is configured, use the no vc-mode raw-pass-through
command to disable VPLS raw pass through mode.
Brocade(config-mpls)# vpls test 100
