ipv6
Syntax [no] ipv6
Context config>service>vprn>interface
Description This command configures an IPv6 interface.
address
Syntax address ipv6-address/mask [eui-64] [preferred]
no address ipv6-address/prefix-length
Context config>service>vprn>interface>ipv6
Description This command assigns an IPv6 address to the VPRN interface.
Parameters ipv6-address/prefix-length — Specifies the IPv6 address on the interface.
Values ipv6-address/prefix: ipv6-address x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x [0 — FFFF]H
d [0 — 255]D
prefix-length 1 — 128
eui-64 — When the eui-64 keyword is specified, a complete IPv6 address from the supplied prefix
and 64-bit interface identifier is formed. The 64-bit interface identifier is derived from MAC
address on Ethernet interfaces. For interfaces without a MAC address, for example ATM
interfaces, the Base MAC address of the chassis is used.
preferred — specifies that the IPv6 address is the preferred IPv6 address for this interface. Preferred
address is an address assigned to an interface whose use by upper layer protocols is unrestricted.
Preferred addresses maybe used as the source (or destination) address of packets sent from (or to)
the interface. Preferred address doesn’t go through the DAD process.

Context config>service>vprn>interface>ipv6
Description This command configures DHCPv6 relay parameters for the VPRN interface.
