Information About Broadband IPv6 Counter Support at LNS

Broadband IPv6 Counter Support at LNS

This feature provides support for broadband PPP IPv6 sessions at the layer 2 tunneling protocol (L2TP) network server (LNS). The sessions are forwarded by L2TP access concentrator (LAC) using layer 2 tunneling protocol L2TP over IPv6.

This feature is enabled automatically when the user configures LNS and enables IPv6.

How to Verify Broadband IPv6 Counter Support at LNS

Verifying Broadband IPv6 Counter Support at the LNS

This feature is enabled automatically when the user configures LNS and enables IPv6. To verify information about this feature, you can use any or all of the following optional commands as needed.

SUMMARY STEPS

    1.    enable

    2.    show l2tp session [all | packets [ipv6] | sequence | state | [brief | circuit | interworking] [hostname]] [ip-addr ip-addr[vcid vcid] | tunnel{id local-tunnel-id local-session-id| remote-name remote-tunnel-name local-tunnel-name}| username username | vcid vcid]

    Step 5 show vpdn session [l2f | l2tp | pptp] [all | packets [ipv6] | sequence | state [filter]]


    Example:
    Router# show vpdn session packets ipv6
     

    Displays session information about active Layer 2 sessions for a virtual private dialup network (VPDN).

     
    Step 6 show vpdn tunnel [l2f | l2tp | pptp] [all [filter] | packets ipv6] [filter] | state [filter] | summary [filter] | transport[filter]]


    Example:
    Router# show vpdn tunnel packets ipv6
