3.1.5.2 Bringing the IP-HTTPS Link Up

After the HTTPS connection is established, the IP-HTTPS client MUST send an HTTP POST request to the configured URI. The POST request SHOULD use content length encoding [RFC2616], and the value SHOULD be set to 18446744073709551615. After receiving a successful HTTP response, the IP-HTTPS client transitions to the LinkUp state.

The IP-HTTPS link is now usable to send and receive IPv6 traffic (including neighbor and router discovery). The default MTU for the IP-HTTPS link is set to the minimum IPv6 MTU of 1280 [RFC2460].

Sections 3.1.5.3 and 3.1.5.4 apply when the IP-HTTPS client is in LinkUp state.
