Setting The Dscp Value Of L2Tp Packets; Assigning A Tunnel Peer To A Vpn - HP MSR Router Series Wan Access Configuration Manual

This feature takes effect on both sent and received L2TP data messages. The L2TP sessions support this
feature if either the LAC or LNS is enabled with this feature.
To enable session flow control:
Step
1. Enter system view.
2. Enter L2TP group view.
3. Enable the session flow
control feature.

Setting the DSCP value of L2TP packets

The DSCP field is the first 6 bits of the IP ToS byte. This field marks the priority of IP packets for forwarding.
This feature sets the DSCP value for the IP packet when L2TP encapsulates a PPP frame into an IP packet.
To set the DSCP value of L2TP packets:
Step
1. Enter system view.
2. Enter L2TP group view.
3. Set the DSCP value of L2TP
packets.

Assigning a tunnel peer to a VPN

By default, the device transmits L2TP control messages and data messages over the public network. With
this feature, the device transmits them in a specific VPN by searching the routing table in that specified
VPN.
When one L2TP endpoint is in a VPN, assign the peer endpoint to the VPN for correct packet forwarding
between the two endpoints.
To configure the VPN for a tunnel peer:
Step
1. Enter system view.
2. Enter L2TP group view.
