fr map ip

Syntax fr map ip { ip-address[ mask ] default } dlci-number[ broadcast [ nonstandard ietf ] compression { frf9 iphc } ]*

undo fr map ip { ip-addressdefault } dlci-number

View Interface view

Parameter ip-address: Peer IP address.

mask: Peer IP mask, used to create a subnet address mapping.

default: Creates a default mapping.

dlci-number: Local virtual circuit number, in the range 16 to 1007.

broadcast: Specifies if broadcast packets can be sent using the map.

nonstandard: The map adopts nonstandard compatible encapsulation format. In this case, only IPHC compression can be adopted. PVC groups does not support compression.

ietf: The map adopts IETF encapsulation format. In this case, only FRF9 and IPHC can be adopted. PVC groups does not support compression.

compression: Enables frame relay compression.

frf9: Adopts payload compression.

iphc: Adopts IP, UDP, or RTP header compression.

Description Use the fr map ip command to add an IP address map entry for frame relay.

Use the undo fr map ip command to remove an IP address map entry for frame relay.

By default, no static address map entry exists and InARP is enabled.

You can create an address map manually or by using InARP. InARP is suitable for a complex network where the remote router also supports InARP. When the number of remote hosts is small or when default routes exist, however, manual map creation is preferred.

Example # Create a static address map entry on interface Serial 2/0, where DLCI 50 is connected to the router with IP address 202.38.163.252.
