Configuring an Accept-Dialin VPDN Group to Preserve IP TOS

To configure an accept-dialin VPDN group to preserve IP TOS, enter the following commands beginning
in global configuration mode:
Command
Step 1
Router(config)# vpdn-group number
Step 2
Router(config-vpdn)# accept-dialin
Step 3
Router(config-acc-in)# protocol l2tp
Step 4
Router(config-vpdn-acc-in)# virtual-template
number
Step 5
Router(config-vpdn-acc-in)# exit
Step 6
Router(config-vpdn)# terminate-from hostname

Step 7
Router(config-vpdn)# local name local-name
Step 8

ip tos reflect
Purpose
Selects the VPDN group and enters VPDN configuration
mode.
Accepts tunneled PPP connections from the LAC and creates
an accept-dialin virtual private dialup network (VPDN)
subgroup.
Specifies the Layer 2 Tunnel Protocol (L2TP) that the VPDN
subgroup will use.
Note L2TP is the only protocol that supports dialout and IP
TOS preservation.
Specifies the virtual template interface to use to clone the new
virtual access interface.
Returns to VPDN group mode.
Specifies the host name of the remote LAC that will be
required when accepting a VPDN tunnel.
Specifies the local host name that the tunnel will use to
identify itself.
Configures the VPDN group to preserve the TOS field of
L2TP tunneled IP packets.
