Headquarters

4. For site-to-site VPNs, apply the SQoS policy to the tunnels

Apply the policy to the VPN between headquarters and branch office 1.

set sqos interface=ipsec-branch1 tunnelpolicy=1

Apply the policy to the VPN between headquarters and branch office 2.

set sqos interface=ipsec-branch2 tunnelpolicy=1

5. For roaming clients, use triggers to apply SQoS to dynamic interfaces

This example creates four triggers, which allows for up to four simultaneous roaming client VPNs. You can scale this to the correct number for your network.

Create the following scripts as text files on the router.

script name

script contents

ppp0up.scp

set sqos int=ppp0 outpolicy=1

 

 

ppp1up.scp

set sqos int=ppp1 outpolicy=1

 

 

 

ppp2up.scp

set

sqos int=ppp2 outpolicy=1

 

 

 

ppp3up.scp

set

sqos int=ppp3 outpolicy=1

 

 

 

Create triggers to run the appropriate script when the interface comes up.

enable trigger

create trigger=1 interface=ppp0 event=up cp=ipcp script=ppp0up.scp create trigger=2 interface=ppp0 event=up cp=ipcp script=ppp1up.scp create trigger=3 interface=ppp0 event=up cp=ipcp script=ppp2up.scp create trigger=4 interface=ppp0 event=up cp=ipcp script=ppp3up.scp

6. For roaming clients, set L2TP TOS reflection

You need TOS (type of service) reflection so that DSCP marked VoIP packets can be classified for prioritisation at the PPP level. Unless you already turned on TOS reflection when you configured L2TP in step 5 on page 10, delete your existing L2TP entry and add it again.

delete l2tp ip=1.1.1.1-255.255.255.254 ppptemplate=1

add l2tp ip=1.1.1.1-255.255.255.254 ppptemplate=1 tos=on

7. Save your configuration

create conf=<your-file.cfg>

set config=<your-file.cfg>
