Modifying an APN Template to Support L2TP
Use the following example to modify APN template to support L2TP:
configure
context ctxt_name
apn apn_name
tunnel l2tp [ peer-address lns_address [ [ encrypted ] secret
l2tp_secret ] [ preference num ] [ tunnel-context tunnel_ctxt_name ] [ local-
address agw_ip_address ] [ crypto-map map_name { [ encrypted ] isakmp-secret
crypto_secret } ]
l2tp_secret ] [ preference num ] [ tunnel-context tunnel_ctxt_name ] [ local-
address agw_ip_address ] [ crypto-map map_name { [ encrypted ] isakmp-secret
crypto_secret } ]
end
Notes:
ctxt_name is the system context in which the APN template is configured.
apn_name is name of the preconfigured APN template in which you want to configure L2TP support.
lns_address is the IP address of the LNS node with which this APN will communicate.
tunnel_ctxt_name is the L2TP context in which the L2TP tunnel is configured.
agw_ip_address is the local IP address of the GGSN in which this APN template is configured.
map_name is the preconfigured crypto map (ISAKMP or manual) which is to use for L2TP.
