Configuring DoD/BoD

XSR(config-if<D2>)#no shutdown

XSR(config-if<D2>)#dialer remote-name XSR-Boston

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 1

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

The following command sets remote user authentication:

XSR(config)#username XSR-toronto password secret 0 code

MLPPP Point-to-Multipoint Configuration

The following configuration, as illustrated in Figure 10-12on page 10-27,sets up a switched MLPPP group (bundle) when Access List-defined data traffic is generated to a remote site.

Note: Only peer Node A can initiate the MLPPP group setup.

Node A (Calling Node) Configuration

The following commands add a dialer pool member with the Central Office switch type to BRI interface 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 25

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

The following commands define a dialer group, add a dialer pool, enable MLPPP, set a 20-second idle timeout, and map BRI interface 1/0 to Dialer interface 1. The min-linkscommand directs the XSR to maintain a minimum of two links over the switched line. The dialer map command directs Node A to call Node B, specifying Node B’s IP address and phone number, as well as enables spoofing.

XSR(config)#interface dialer 1

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

XSR(config-if<D1>)#dialer pool 25

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

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

XSR(config-if<D1>)#dialer-group 3

XSR(config-if<D1>)#dialer map ip 10.10.10.2 2400

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

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

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

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

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

The following command maps ACL 101 to dialer group 3:

XSR(config)#dialer-list 3 protocol ip list 101
