Manually Configuring L2TPv3 Session Parameters

When you bind an attachment circuit to an L2TPv3 pseudowire for Xconnect service using the xconnect

l2tpv3 manual command (see the section “Configuring the Xconnect Attachment Circuit”) because you

do not want signaling, you must then configure L2TP-specific parameters to complete the L2TPv3

control channel configuration.

SUMMARY STEPS

1. enable

2. configure terminal

3. interface type slot/port

4. xconnect peer-ip-address vc-id encapsulation l2tpv3 manual pw-class pw-class-name

5. l2tp id local-session-id remote-session-id

6. l2tp cookie local size low-value [high-value]

7. l2tp cookie remote size low-value [high-value]

8. l2tp hello l2tp-class-name

DETAILED STEPS

Command or Action Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

• Enter your password if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

interface type slot/port

Example:

Router(config)# interface ethernet 0/0

Specifies the interface by type (for example, Ethernet) and

slot and port number, and enters interface configuration

mode.

Step 4

xconnect peer-ip-address vc-id encapsulation

l2tpv3 manual pw-class pw-class-name

Example:

Router(config-if)# xconnect 10.0.3.201 123

encapsulation l2tpv3 manual pw-class

vlan-xconnect

Specifies the IP address of the peer PE router and the 32-bit

virtual circuit identifier shared between the PE at each end

of the control channel.

• The peer router ID (IP address) and virtual circuit ID

must be a unique combination on the router.

• The encapsulation l2tpv3 manual parameter specifies

that L2TPv3 is to be used as the pseudowire tunneling

method, and enters xconnect configuration mode.

• The mandatory pw-class pw-class-name keyword and

argument combination specifies the pseudowire class

configuration from which the data encapsulation type

(L2TPv3) will be taken.
