Configuring TTL for L2TPv3 over IPv6 Tunnels
Perform this task to configure time to live (TTL) for L2TPv3 over IPv6 tunnels.
SUMMARY STEPS
1. configure
2. l2vpn
3. pw-class class-name
4. encapsulation l2tpv3
5. protocol l2tpv3
6. ttl value
7. Use the commit or end command.
DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router # configure
Enters the Global Configuration mode.
Step 2 l2vpn
Example:
RP/0/RSP0/CPU0:router (config)# l2vpn
Enters Layer 2 VPN configuration mode.
Step 3 pw-class class-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
