Configuring frame relay address mappings
Configure frame relay address mappings in one of the following ways:
Manually create static mappings between remote IP addresses and local DLCIs. Use this method when the network topology is relatively stable and no new users are expected in a certain period of time. Because static mappings do not change, the network connections are stable, and attacks from unknown users are avoided.
Use InARP or IND to dynamically create mappings between peer IP addresses and local DLCIs. Use this method in complicated networks and make sure the peer device also supports InARP or IND.
Configuration guidelines
Do not configure DLCIs for PVCs if IPv4 or IPv6 static address mappings are configured.
Do not configure IPv4 or IPv6 static address mappings on a P2P subinterface. A P2P subinterface carries only one PVC.
IPv6 does not support nonstandard mappings.
Configuring IPv4 frame relay address mappings
To onfigure IPv4 static frame relay address mappings:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Create an IPv4 static frame relay address mapping. | fr map ip { ip-address [ mask ] | default } dlci-number [ broadcast | [ ietf | nonstandard ] ] * [ compression { frf9 | iphc connections number } ] | By default, no IPv4 static frame relay address mappings are configured. |
To configure IPv4 dynamic frame relay address mappings:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Enable InARP for IPv4 dynamic frame relay address mappings. | fr inarp [ ip [ dlci-number ] ] | Optional. By default, InARP is enabled for IPv4 dynamic frame relay address mappings. |
Configuring IPv6 frame relay address mappings
To onfigure IPv6 static frame relay address mappings:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Create an IPv6 static frame relay address mapping. | fr map ipv6 { ipv6-address | default } dlci-number [ broadcast ] [ {compression frf9} ] | By default, no IPv6 static frame relay address mappings are configured. |
To configure IPv6 dynamic frame relay address mappings:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Enable IND for IPv6 dynamic frame relay address mappings. | fr ipv6 ind [ dlci-number ] | Optional. By default, IND is enabled for IPv6 dynamic frame relay address mappings. |
4. Set the IND packet transmission interval after IPv6 IND is enabled. | ipv6 ind holdtime time-value | Optional. By default, the IND packet transmission interval is 30 seconds. |
