You should configure Multilink PPP if the following conditions exist in your network:<br />

• Point-to-point connection using PPP Encapsulation<br />

• Slow links<br />

Note Multilink PPP should not be used on links greater than 2 Mbps.<br />

Configure Multilink PPP with Interleaving<br />

Multilink PPP sup<strong>port</strong> for interleaving can be configured on virtual templates, dialer interfaces, and<br />

ISDN BRI or PRI interfaces. To configure interleaving, you need to complete the following tasks:<br />

• Configure the dialer interface or virtual template, as <strong>de</strong>fined in the relevant chapters of the<br />

Cisco IOS Release 11.3 Dial Solutions Configuration Gui<strong>de</strong>.<br />

• Configure Multilink PPP and interleaving on the interface or template.<br />

To configure Multilink PPP and interleaving on a configured and operational interface or virtual<br />

interface template, use the following commands in interface mo<strong>de</strong>:<br />

Step Command Purpose<br />

1 ppp multilink Enable Multilink PPP.<br />

2 ppp multilink interleave Enable real-time packet interleaving.<br />

3 ppp multilink fragment-<strong>de</strong>lay milliseconds Optionally, configure a maximum fragment<br />

<strong>de</strong>lay.<br />

4 ip rtp reserve lowest-UDP-<strong>port</strong><br />

range-of-<strong>port</strong>s [maximum-bandwidth]<br />

Note The ip rtp reserve command can be used instead of configuring RSVP. If you configure<br />

RSVP, this command is not required.<br />

For more information about Multilink PPP, refer to the “Configuring Media-In<strong>de</strong>pen<strong>de</strong>nt PPP and<br />

Multilink PPP” chapter in the Cisco IOS Release 11.3 Dial Solutions Configuration Gui<strong>de</strong>.<br />

Multilink PPP Configuration Example<br />

The following example <strong>de</strong>fines a virtual interface template that enables Multilink PPP with<br />

interleaving and a maximum real-time traffic <strong>de</strong>lay of 20 milliseconds, and then applies that virtual<br />

template to the Multilink PPP bundle:<br />

interface virtual-template 1<br />

ppp multilink<br />

encapsulated ppp<br />

ppp multilink interleave<br />

ppp multilink fragment-<strong>de</strong>lay 20<br />

ip rtp reserve 16384 100 64<br />

multilink virtual-template 1<br />

Reserve a special queue for real-time packet<br />

flows to specified <strong>de</strong>stination User Datagram<br />

Protocol (UDP) <strong>port</strong>s, allowing real-time traffic<br />

to have higher priority than other flows. This is<br />

only applicable if you have not configured<br />

RSVP.<br />
