Mapping a Protocol Address to a PVC Using Static Map Lists
You can create multiple map lists, but only one map list can be associated with an interface. Different
map lists can be associated with different interfaces.
Example
Figure 13-2 illustrates a connection configured with a PVC map list.
Figure 13-2 PVC Map List Configuration Example
The following example shows the commands used to configure the connection in Figure 13-2.
Switch(config)# interface atm 0
Switch(config-if)# ip address 1.1.1.1 255.0.0.0
Switch(config-if)# map-group yyy
Switch(config-if)# atm pvc 0 200 interface atm 3/0/0 100 300 encap aal5snap
Switch(config-if)# exit
Switch(config)# ip route 1.1.1.1 255.0.0.0 1.1.1.2
Switch(config)# map-list yyy
Switch(config-map-list)# ip 1.1.1.2 atm-vc 200
Step 4
Switch(config-if)# atm pvc vpi-a vci-a [upc upc]
[pd pd] [rx-cttr index] [tx-cttr index] interface
atm card/subcard/port[.vpt#] vpi-b vci-b
[upc upc] [encap aal-encap]
Configures the PVC.
Step 5
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode.
Step 6
Switch(config)# ip route ip-address mask
forward-ip address
Configures an IP route to the router.
Step 7
Switch(config)# map-list name
Switch(config-map-list)#
Creates a map list by naming it, and enters
map-list configuration mode.
Step 8
Switch(config-map-list)# ip ip-address
{atm-nsap address | atm-vc vci} [aal5mux
encapsulation] [broadcast pseudo-broadcast]
[class class-name]
Associates a protocol and address to a specific
virtual circuit.
Command Purpose
IF# = 3/0/0
IP address = 1.1.1.1
VPI = 0, VCI = 200
VPI = 100, VCI = 300
IF# = 1/0
