Configuring BAP
3.
Configure the Dialer 1 interface with a dialer pool:
XSR2(config)#interface Dialer1
XSR2(config-if<D1>)#no shutdown
XSR2(config-if<D1>)#dialer pool 1
XSR2(config-if<D1>)#encapsulation ppp
4.
Set up BAP on Dialer 1 by enabling BAP and adding BAP phone numbers for XSR1 to call.
XSR2(config-if<D1>)#ppp multilink bap
XSR2(config-if<D1>)#ppp bap number default 3101
XSR2(config-if<D1>)#ppp bap number default 3102
XSR2(config-if<D1>)#ppp bap number default 3103
XSR2(config-if<D1>)#ppp bap number default 3104
XSR2(config-if<D1>)#ppp bap number default 3105
XSR2(config-if<D1>)#ip address 99.99.1.1 255.0.0.0
Dual XSRs: BAP Using Call/Callback Request
The following example sets up BAP between two XSRs, with XSR1 configured to perform Dial on
Demand (DoD) and request additional links by sending a callback request to XSR2, which also is
configured with DoD and requests additional links with call requests to XSR1.
XSR1 Configuration
XSR1(config)#controller e1 2/0
XSR1(config-controller<T1-2/0>)#pri-group
XSR1(config-controller<T1-2/0>)#no shutdown
!
XSR1(config)#interface Dialer1
XSR1(config-if<D1>)#no shutdown
XSR1(config-if<D1>)#dialer pool 1
XSR1(config-if<D1>)#encapsulation ppp
XSR1(config-if<D1>)#multilink load-threshold 3
XSR1(config-if<D1>)#ppp multilink bap
XSR1(config-if<D1>)#ppp bap number default 3200
XSR1(config-if<D1>)#ppp bap callback request
XSR1(config-if<D1>)#dialer-group 2
XSR1(config-if<D1>)#dialer map ip 10.10.10.2 1300
XSR1(config-if<D1>)#ip address 10.10.10.1 255.255.255.0
XSR1(config)#access-list 102 permit icmp any any 8

XSR2 Configuration
XSR2(config)#controller e1 2/0

XSR2(config-controller<T1-2/0>)#dial pool-member 1
