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
command enables BoD by making the
XSR maintain three links over the switched line. The
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
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
