Configuring Classical IP over ATM in an SVC Environment
NSAP Address Example
Figure 24-7 shows three ATM switch routers and a router connected using classical IP over ATM.
Figure 24-7 Classical IP over ATM Connection Setup
The following example shows how to configure the ATM router module interface ATM 1/0/0 of Client A
in Figure 24-7, using the NSAP address:
Client A(config)# interface atm 1/0/0
Client A(config-if)# atm nsap-address 47.0091.8100.0000.1111.1111.1111.1111.1111.1111.00
Client A(config-if)# ip address 123.233.45.1 255.255.255.0
Client A(config-if)# atm arp-server nsap 47.0091.8100.0000.1111.1111.1111.2222.2222.2222.00
Client A(config-if)# exit
Client A(config)# atm route 47.0091.8100.0000.1111.1111.1111.1111.1111.1111 atm 1/0/0 internal
ESI Example
The following example shows how to configure the ATM router module interface ATM 1/0/0 of Client A
in Figure 24-7, using the ESI:
Client A(config)# interface atm 1/0/0
Client A(config-if)# atm esi-address 0041.0b0a.1081.40
Client A(config-if)# ip address 123.233.45.1 255.255.255.0
Client A(config-if)# atm arp-server nsap 47.0091.8100.0000.1111.1111.1111.2222.2222.2222.00
Client A(config-if)# exit
