396 CHAPTER 22: FRAME RELAY CONFIGURATION COMMANDS
fr map ip
Syntax fr map ip { ip-address [ mask ] | default } dlci-number [ broadcast | [ nonstandard |
ietf ] | compression { frf9 | iphc }]*
undo fr map ip { ip-address | default } 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.
