Switched PPP Multilink Configuration

Node A (Calling Node) Configuration

The following commands add a dialer pool member and set the Central Office switch type on BRI port 1/0:

XSR(config)#interface bri 1/0

XSR(config-if<BRI-1/0>)#isdn switch-type basic-net3

XSR(config-if<BRI-1/0>)#dialer pool-member 23

XSR(config-if<BRI-1/0>)#no shutdown

The following commands define a dialer group, add a dialer pool, enable MLPPP, set a load threshold of 3 links, and map BRI interface 1/0 to Dialer interface 1. The load-thresholdcommand enables BoD by making the

XSR maintain three links over the switched line. The dialer map command directs Node A to call Node C, specifying Node C’s IP address and phone number as well as enables spoofing on the network.

XSR(config)#interface dialer 1

XSR(config-if<D1>)#no shutdown

XSR(config-if<D1>)#dialer pool 23

XSR(config-if<D1>)#encapsulation ppp

XSR(config-if<D1>)#ip address 10.10.10.1 255.255.255.0

XSR(config-if<D1>)#dialer map ip 10.10.10.3 2500

XSR(config-if<D1>)#ppp multilink

XSR(config-if<D1>)#dialer-group 7

XSR(config-if<D1>)#multilink load-threshold 3

XSR(config-if<D1>)#dialer idle-timeout 20

The following command defines interesting packets for the dial out trigger by configuring ACL 106 to pass all Type 8 source and destination ICMP packets up to 20 idle seconds:

XSR(config)#access-list 106 permit icmp any any 8

The following command maps ACL 106 to dialer group 7:

XSR(config)#dialer-list 7 protocol ip list 106

Node C (Called Node) Configuration

The following commands add a dialer pool member and set the Central Office switch type on BRI port 1/0:

XSR(config)#interface bri 1/0

XSR(config-if<BRI-1/0>)#isdn switch-type basic-net3

XSR(config-if<BRI-1/0>)#dialer pool-member 2

XSR(config-if<BRI-1/0>)#no shutdown

The following commands add a dialer pool, enable MLPPP, and map BRI interface 1/0 to Dialer interface 1. The dialer called command maps incoming Node A calls to its 2500 number:

XSR(config)#interface dialer 1

XSR(config-if<D1>)#no shutdown

XSR(config-if<D1>)#dialer pool 2

XSR(config-if<D1>)#encapsulation ppp

XSR(config-if<D1>)#dialer called 2500

XSR(config-if<D1>)#ip address 10.10.10.3 255.255.255.0

XSR(config-if<D1>)#ppp multilink
