Configuring Layer 2 Tunneling Per-VLAN

Chapter 9 Configuring IEEE 802.1Q Tunneling and Layer 2 Protocol Tunneling on the ML-Series Card

Configuring Layer 2 Protocol Tunneling

Beginning in privileged EXEC mode, follow these steps to configure a VLAN as a Layer 2 tunnel VLAN:

	Command	Purpose
Step 1
Step 1	ML_Series# configuration terminal	Enters global configuration mode.
Step 2
Step 2	ML_Series(config)# bridge	Creates a bridge group number and specifies a protocol.
	bridge-group-number protocol type
Step 3
Step 3	ML_Series(config)# l2protocol-tunnel	Associates a CoS value with the Layer 2 tunneling VLAN. Valid
	cos cos-value	numbers for cos-valuerange from 0 to 7.
Step 4
Step 4	ML_Series(config)# interface type	Enters subinterface configuration mode and the subinterface to be
	number.subinterface-number	configured as a tunnel VLAN.
Step 5
Step 5	ML_Series(config-subif)# encapsulation	Sets the subinterface as an IEEE 802.1Q tunnel VLAN.
	dot1q bridge-group-number
Step 6
Step 6	ML_Series(config-subif)# bridge-group	Specifies the default VLAN, which is used if the subinterface stops
	bridge-group-number	trunking. This VLAN ID is specific to the particular customer.
Step 7
Step 7	ML_Series(config-subif)# end	Returns to privileged EXEC mode.
Step 8
Step 8	ML_Series# copy running-config	(Optional) Saves your entries in the configuration file.
	startup-config
