# ipv6 unnumbered

#### Syntax

ipv6 unnumbered interfaceType interfaceSpecifier

no ipv6 unnumbered

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Enables or disables IPv6 processing on an interface without assigning an explicit IPv6 address to that interface. The global IPv6 address of the interface, specified by the interfaceType interfaceSpecifier values, becomes the source address in packets that the unnumbered interface generates. The no version of the command removes the IPv6 address from the interface.

| Note: Enabling IPv6 on an interface automatically configures the link-local address on an unnumbered interface.
