11.3. Examples |
|
|
|
The following addresses |
|
|
|
fe80::1234 (on the 1st link of the node) |
|
ff02::5678 (on the 5th link of the node) |
|
ff08::9abc (on the 10th organization of the node) |
|
|
|
would be represented as follows: |
|
|
|
fe80::1234%1 |
|
ff02::5678%5 |
|
ff08::9abc%10 |
|
|
|
(Here we assume a natural translation from a zone index to the |
|
<zone_id> part, where the Nth zone of any scope is translated into |
|
"N".) |
|
|
|
If we use interface names as <zone_id>, those addresses could also be |
|
represented as follows: |
|
|
|
fe80::1234%ne0 |
|
ff02::5678%pvc1.3 |
|
ff08::9abc%interface10 |
|
|
|
where the interface "ne0" belongs to the 1st link, "pvc1.3" belongs |
|
to the 5th link, and "interface10" belongs to the 10th organization. |
