Enabling TOS Reflection in the L2TPv3 Header
Enters Layer 2 VPN configuration mode.
Step 3
pw-classclass-name
Example:
RP/0/RSP0/CPU0:router (config-l2vpn)# pw-class l2tpv3_class
Enters pseudowire class submode, and allows a pseudowire class template definition.
Step 4 encapsulation l2tpv3
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-pwc)# encapsulation l2tpv3
Sets pseudowire encapsulation to L2TPv3.
Step 5
protocol l2tpv3
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-pwc-encap-l2tpv3)# protocol l2tpv3
Sets pseudowire signaling protocol to L2TPv3.
Step 6 neighbor ipv6peer-address pw-id pseudowire-id
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-xc-p2p)# neighbor ipv6 1111:2222::cdef pw-id
Specifies the peer with which to cross connect, and configures the pseudowire segment for the cross-connect.
Step 7
tos { reflect | value }
Example:
RP/0/RSP0/CPU0:router (config-l2vpn-pwc-encap-l2tpv3)# tos reflect
or
RP/0/RSP0/CPU0:router (config-l2vpn-pwc-encap-l2tpv3)# tos value 50
Enables type of service (TOS) reflection. As a result, copies TOS from inner IP header to the L2TPv3 header.
Additionally, use this command to set the value of TOS for the L2TPv3 pseudowire class. The range is from 0 to 255.
Step 8
endorcommit
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-pwc-encap-l2tpv3)# end
or
RP/0/RSP0/CPU0:router(config-l2vpn-pwc-encap-l2tpv3)# commit
Saves configuration changes.
• When you issue the end command, the system prompts you to commit changes:
Uncommitted changes found, commit them before exiting(yes/no/cancel)?[cancel]:
• Entering yes saves configuration changes to the running configuration file, exits the configuration session, and
returns the router to EXEC mode.
• Entering no exits the configuration session and returns the router to EXEC mode without committing the
configuration changes.
