configure bootprelay ipv6 prefix-delegation snooping add ipv6_prefix ipv6Gateway {vlan} vlan_name valid-time valid_time

Description

Adds information about a snooped IPv6 delegated prefix on a VLAN.

Syntax Description

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.

Default

N/A

Usage Guidelines

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 .

Example

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
