Implementing Layer 2 Tunnel Protocol Version 3
SUMMARY STEPS
1. configure
2. l2tp-class l2tp-class-name
3. receive-window size
4. retransmit { initial retries initial-retries | retries retries | timeout { max | min } timeout }
5. timeout setup seconds
DETAILED STEPS
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2
l2tp-class l2tp-class-name
Example:
RP/0/RP0/CPU0:router(config)#
Specifies the L2TP class name and enters L2TP class configuration mode.
Step 3
receive-window size
Example:
RP/0/RP0/CPU0:router(config-l2tp-class)# receive-window 30
Configures the number of packets that can be received by the remote peer before backoff queueing occurs.
The default value is 512.
Step 4
retransmit { initial retries initial-retries | retries retries | timeout { max | min } timeout }
Example:
RP/0/RP0/CPU0:router(config-l2tp-class)# retransmit retries 10
Configures parameters that affect the retransmission of control packets.
• initial retries—Specifies how many SCCRQs are re-sent before giving up on the session. Range is 1 to 1000. The
default is 2.
• retries—Specifies how many retransmission cycles occur before determining that the peer PE router does not
respond. Range is 1 to 1000. The default is 15.
• timeout { max | min }—Specifies maximum and minimum retransmission intervals (in seconds) for resending
control packets. Range is 1 to 8. The default maximum interval is 8; the default minimum interval is 1.
