2.0Â Â Common IPv4 and IPv6 Allocations
OLD:
 Â
  IANA SHALL assign SCTP port number TBD1 for use by experimental mobility
  protocols such as Seamoby. See Section 5.2.1 of [CARD] for a description
of inter-access router CARD protocol use of SCTP, and Section 3.1 of [CTP]
for a description of the inter-access router CTP use of SCTP.
  IANA SHALL assign SCTP Payload Protocol Identifier (PPI) TBD2, designated
  "CTP", for the Context Transfer Protocol, and SCTP Payload Protocol
  Identifier TBD3, designated "CARD", for the Candidate Access Router
  Discovery protocol. These are used to differentiate inter-router CARD and
  CTP messages on the SCTP port. The allocation policy for new PPI
numbers is the method of IETF Consensus Action.
NEW:
  IANA shall assign SCTP port numbers TBD1 for use by [CARD] and
TBD1a for use of [CTP]. See Section 5.2.1 of [CARD] for a description of
  inter-access router CARD protocol use of SCTP, and Section 3.1 of [CTP]
  for a description of the inter-access router CTP use of SCTP.

Section 9
OLD:
9.0Â Â Utilization by Other Experimental Mobility Protocols
  The ICMP Experimental Mobility type code and SCTP port are available for
  other experimental mobility protocols to utilize. Other experimental
  mobility protocols MAY define additional ICMP messages that utilize the
  code points under the Experimental Mobility ICMP type, and MAY define
  protocols that utilize additional SCTP PPI numbers for the Experimental
  Mobility protocol port.
NEW:
9.0Â Â Usage by Other Experimental Mobility Protocols
  The ICMP Experimental Mobility type code is available for
  other experimental mobility protocols to use. Other experimental
  mobility protocols MAY define additional ICMP messages that use
code points under the Experimental Mobility ICMP type.
