IPV6CP, PPP IPv6 Control Protocol

Description Glossary RFCs Publications Obsolete RFCs

Description:

Protocol suite: PPP.
Protocol type:PPP network control protocol.
PPP Protocol:0x8057.
SNMP MIBs:
Working groups:
Links: IANA: PPP Assigned numbers.

The IPV6CP protocol is used for establishing and configuring IPv6 over PPP links.

RFC 2472, pages 1 - 3:

Before any IPv6 packets may be communicated, PPP MUST reach the Network-Layer Protocol phase and the IPv6 Control Protocol MUST reach the Opened state.

IPV6CP is responsible for configuring, enabling, and disabling the IPv6 protocol modules on both ends of the point-to-point link. IPV6CP uses the same packet exchange mechanism as the Link Control Protocol (LCP). IPV6CP packets may not be exchanged until PPP has reached the Network-Layer Protocol phase. IPV6CP packets received before this phase is reached should be silently discarded.
