3Com Router 5000 Family and Router 6000 Family map ip ● 221
Command Reference
map ip
Purpose Use the map ip command to create IPoA mapping for PVC.
Use the undo map ip command to delete the mapping.
Syntax map ip { ip-address [ ip-mask ] | default | inarp [ minutes ] } [
broadcast ]
undo map ip { ip-address | default | inarp }
Parameters ip-address
Opposite IP address mapping to PVC.
ip-mask
IP address mask, optional. If a packet cannot find the
next hop at the interface, but the next hop address
belongs to the network segment specified by
ip-address and ip-mask, it can be sent over the
PVC.
default
A mapping with the default route property is set. If a
packet cannot find a mapping with the same address
of next hop at the interface, but one PVC has the
default mapping, the packet can be sent over the PVC.
inarp
Enables Inverse Address Resolution Protocol (InARP) at
PVC.
minutes
Time interval to send InARP packets in minutes,
optional. The range of the value is 1 to 600 and the
default value is 15.
broadcast
Pseudo-broadcast, an optional keyword parameter. If
the IPoA map of the PVC is configured with
pseudo-broadcast, the router sends on the PVC a copy
of each broadcast packet that it sends out the
interface to which the PVC belongs. You must
configure the broadcast keyword on an ATM PVC
where broadcast or multicast packets must be sent, for
example, to allow PIM multicast to create neighbor
relationship with the router connected using the ATM
interface.
Default By default, no mapping is configured. If a mapping is set, pseudobroadcast is not
supported by default.
Example The two examples are the cases creating IPoA mapping for PVC.
Display how to create a static mapping at PVC 1/32, specify the opposite IP address to
61.123.30.169 and support pseudobroadcast.
