The lsa-forwarding-address command enables the OSPFv3 forwarding address (FA) function.
The undo lsa-forwarding-address command disables the OSPFv3 FA function.
By default, the OSPFv3 FA function is disabled.
| Parameter | Description | Value |
|---|---|---|
| standard | Indicates that the function is compatible with RFC 3101. | - |
| zero-translate | Allows the Type 7 LSAs with the P-bit set and the FA being 0 to be translated to Type 5 LSAs. | - |
The FA in an OSPFv3 Type 5 or Type 7 LSA is used to notify the devices in the local routing domain of the shortcut next hop to the AS external network described in the LSA. This prevents internal devices from routing packets to themselves as the next hop before forwarding the packets to the devices in the external routing domain on the same broadcast network.
To enable the OSPFv3 FA function, run the lsa-forwarding-address { standard | zero-translate } command.
