Configuring global SAVI
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enable the SAVI function. | ipv6 savi strict | Disabled by default. |
3. Setting the deletion delay time for SAVI. | ipv6 savi down-delay time | The default setting is 30 seconds. |
4. Set the time to wait for a duplicate address detection (DAD) NA. | ipv6 savi dad-delay value | Optional One second by default. If no DAD NA is received within the specified time when the corresponding ND snooping entry is in detect state, the ND snooping entry changes to bound state. |
5. Set the time to wait for a DAD NS from a DHCPv6 client. | ipv6 savi dad-preparedelay value | Optional One second by default. This command is used with the DHCPv6 snooping function. After DHCPv6 snooping detects that a client obtains an IPv6 address, it monitors whether the client detects IP address conflict. If DHCPv6 snooping does not receive any DAD NS from the client before the set time expires, SAVI sends a DAD NS on behalf of the client. |
