Chapter 13 Configuring IP over ATM
Configuring Classical IP over ATM
Example
The following example configures the route processor interface ATM 0 as an ARP server (shown in
Figure 13-1):
ARP_Server(config)# interface atm 0
ARP_Server(config-if)# atm esi-address 0041.0b0a.1081.00
ARP_Server(config-if)# atm arp-server self
ARP_Server(config-if)# ip address 123.233.45.2 255.255.255.0
Client A(config)# atm route 47.0091.8100.0000.1111.1111.1111.1111.1111.1111 atm 0 internal
Displaying the IP-over-ATM Interface Configuration
To show the IP-over-ATM interface configuration, use the following EXEC commands:
Examples
In the following example, the show atm arp-server command displays the configuration of the interface
ATM 0:
Switch# show atm arp-server
Note that a '*' next to an IP address indicates an active call
IP Address TTL ATM Address
ATM2/0/0:
* 10.0.0.5 19:21 4700918100567000000000112200410b0a108140
The following example displays the map-list configuration of the static map and IP-over-ATM
interfaces:
Switch# show atm map
Map list ATM2/0/0_ATM_ARP : DYNAMIC
arp maps to NSAP 36.0091810000000003D5607900.0003D5607900.00
, connection up, VPI=0 VCI=73, ATM2/0/0
ip 5.1.1.98 maps to s 36.0091810000000003D5607900.0003D5607900.00
, broadcast, connection up, VPI=0 VCI=77, ATM2/0/0
Map list ip : PERMANENT
ip 5.1.1.99 maps to VPI=0 VCI=200
Configuring Classical IP over ATM in a PVC Environment
This section describes how you configure classical IP over ATM in a permanent virtual channel (PVC)
environment. The ATM Inverse ARP (InARP) mechanism is applicable to networks that use PVCs,
where connections are established but the network addresses of the remote ends are not known. A server
function is not used in this mode of operation.
Command Purpose
show atm arp-server Shows the ATM interface ARP configuration.
show atm map Shows the ATM map list configuration.
