Adds information about a snooped IPv6 delegated prefix on a VLAN (Virtual LAN).
| ipv6_prefix | Specifies the IPv6 prefix (/prefix length) to be added. |
| ipv6Gateway | Specifies the IPv6 gateway address. |
| vlan_name | Specifies the VLAN. |
| valid_time | Time, in seconds, that the delegated IPv6 prefix is valid. |
N/A
Allows you to add a particular IPv6 delegated prefix to snoop if the prefix was issued or renewed during reboot. If the prefix has been snooped earlier, this command renews the valid time for the prefix.
To set the specified prefix to always be valid, set the valid-time parameter to 0.
Before adding an IPv6 delegated prefix to snoop, you must enable IPv6 BOOTP relay and prefix snooping using enable bootprelay ipv6 and configure bootprelay ipv6 prefix-delegation snooping .
The following example adds prefix /56.
configure bootprelay ipv6 prefix-delegation snooping add 5001:db8:3553:bf00::/56 fe80::a440:cfd5:c05b:d324 vlan v1 valid-time 300
