Configuring IP over ATM
Example
The following example configures the route processor interface ATM 0 as an ARP server (shown in
Figure
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:
Command
show atm arp-server
show atm map
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
ATM2/0/0:
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
ip 5.1.1.98 maps to s 36.0091810000000003D5607900.0003D5607900.00
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.
