Configuring DoD/BoD

XSR(config-if<D1>)#dialer pool 1

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

The following commands add a dialer pool member and specify the primary-ni switch on XSR- Toronto’s T1 interface 2/3:

XSR(config)#controller t1 2/3

XSR(config-controller<T1-1/1>)#switch-type primary-ni

XSR(config-controller<T1-1/1>)#dialer pool-member 1

XSR(config-controller<T1-1/1>)#no shutdown

Dial-out Router Example

The following commands add a dialer pool and dialer group and specify the call destination - XSR-Torontoon XSR-Andover’sDialer interface 1.

XSR(config)#interface dialer 1

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

XSR(config-if<D1>)#ip address 172.22.85.2

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

XSR(config-if<D1>)#multilink min-links 2

+Brings up a minimum of 2 links on XSR-Andover’s Dialer interface 1

XSR(config-if<D1>)#dialer pool 1 XSR(config-if<D1>)#no shutdown XSR(config-if<D1>)#dialer string 47410 XSR(config-if<D1>)#dialer-group 1

These commands add a pool member and configure the primary-ni switch on T1 interface 2/3:

XSR(config)#controller t1 2/3

XSR(config-controller<T1-2/3>)#switch-type primary-ni

XSR(config-controller<T1-2/3>)#dialer pool-member 1

XSR(config-controller<T1-2/3>)#no shutdown

The following command maps ACL 101 to dialer group 1:

XSR(config)#dialer-list 1 protocol ip list 101

The following command defines interesting packets for the dial out trigger by configuring ACL 101 to pass all Type 8 source and destination ICMP traffic up to 20 idle seconds:

XSR(config)#access-list 101 permit icmp any any 8

MLPPP Point-to-Multipoint Configurations

The following MLPPP point-to-multipoint topology can be used for BoD applications, as illustrated by Figure 10-15. This example creates multiple switched lines linking users on XSR- Toronto’s network with those on three remote networks.
