ipv6 dhcp-client

vpn 0 interface ipv6 dhcp-client—Configure an interface in the WAN transport VPN (VPN 0) to receive its IPv6 address from a DHCPv6 server. To configure the interface's IPv6 address as a static address, use the ipv6 address command.

You can configure IPv6 only on WAN transport interfaces, that is, only on interfaces in VPN 0.

Administrative Distance
dhcp-distance number
Set the administrative distance of routes learned from a DHCP server.
Range: 1 through 255
Default: 1
Rapid Commit
Enable the DHCPv6 rapid commit option to speed up the assignment of IP addresses. Rapid commit uses a two-message exchange to expedite address assignment.


Configure an IPv6 WAN transport interface to use a dynamic IPv6 address, and enable the rapid commit option for DHCPv6:

vEdge(config)# vpn 0 interface ge0/3
vEdge(config-interface)# ip6 dhcp-client
vEdge(config-interface)# no shutdown
vEdge(config-interface)# tunnel-interface
vEdge(config-tunnel-interface)# color green
vEdge(config-tunnel-interface)# encapsulation ipsec
vEdge(config-tunnel-interface)# commit and-quit
