Step 1 Modify the APN template to support L2TP with LNS server address and other parameters by applying the example
configuration in the Assigning LNS Peer Address in APN Template section.
Step 2
Optional. If L2TP will be used to tunnel transparent IP PDP contexts, configure the APN's outbound username and
password by applying the example configuration in the Configuring Outbound Authentication section.
Step 3

context <dst_ctxt_name> [-noconfirm]
apn <apn_name>
tunnel l2tp [ peer-address <lns_address> [ [ encrypted ] secret <l2tp_secret> ]
[ preference <integer> ] [ tunnel-context <l2tp_context_name> ] [ local-address
<local_ip_address> ] [ crypto-map <map_name> { [ encrypted ] isakmp-secret
<crypto_secret> } ]
end
