Configuring MLPPP on a Multilink/Dialer interface

Multilink Example

The following example enables Multi-Class MLPPP on interfaces 71, 72 and 73 with different

fragmentation delay intervals but permits multicast traffic in and out of the firewall on each

multilink interface. Additionally, Multilink interface 73 is configured to receive and transmit IP

RIP v2 update packets.

XSR(config)#interface multilink 71
XSR(config-if<M71>)#ppp multilink fragment-delay 50
XSR(config-if<M71>)#ppp multilink multi-class
XSR(config-if<M71>)#ip address 15.1.2.70 255.255.255.0
XSR(config-if<M71>)#ip firewall disable
XSR(config-if<M71>)#ip firewall ip-multicast in
XSR(config-if<M71>)#ip firewall ip-multicast out
XSR(config-if<M71>)#no shutdown
XSR(config)#interface multilink 72
XSR(config-if<M72>)#ppp multilink fragment-delay 1000
XSR(config-if<M72>)#ppp multilink multi-class
XSR(config-if<M72>)#ip address 15.1.4.70 255.255.255.0
XSR(config-if<M72>)#ip firewall disable
XSR(config-if<M72>)#ip firewall ip-multicast in
XSR(config-if<M72>)#ip firewall ip-multicast out
XSR(config-if<M72>)#no shutdown
XSR(config)#interface multilink 73
XSR(config-if<M73>)#ppp multilink fragment-delay 650
XSR(config-if<M73>)#ppp multilink multi-class
XSR(config-if<M73>)#ip address 15.1.6.70 255.255.255.0
XSR(config-if<M73>)#ip firewall disable
XSR(config-if<M73>)#ip firewall ip-multicast in
XSR(config-if<M73>)#ip firewall ip-multicast out
XSR(config-if<M73>)#ip rip send version 2
XSR(config-if<M73>)#ip rip receive version 2
XSR(config-if<M73>)#no shutdown

Dialer Example

The following example enables Multi-Class MLPPP on Dialer interface 255 with dialer pool and

BAP settings, Multi-Class fragment delay and load threshold values, and permission allowing

multicast traffic in and out of the firewall on Dialer interface 255:

XSR(config)#interface dialer 255
XSR(config-if<D255>)#dialer pool 255
XSR(config-if<D255>)#dialer redial attempts 60000
XSR(config-if<D255>)#dialer string 9058883300
XSR(config-if<D255>)#dialer string 9058883400
XSR(config-if<D255>)#encapsulation ppp
XSR(config-if<D255>)#multilink load-threshold 190
