CGN Deployment with BGP/MPLS IP VPNs

IETF84 Vancouver

Baseline

Baseline

  • First Presented in BEHAVE at IETF78 – Maastricht

  • Presented to OPSAWG at IETF83 – Paris

  • Accepted as OPSAWG WG Document

  • Potential Move to SUNSET4 in the future (up to AD)

    • (did not exist at the time)

  • Show real world implementation option for CGN (based on NAT444 Model)

  • Includes models for IPv6 Dual Stack with CGN/NAT444

  • Can be used in Wireless or Wireline domains


Status

Status

  • Some, but not too much chatter (comments) on draft from WG

  • Move to SUNSET4 unknown at this time

  • Model in document in production (Wireless/Wireline environments)

  • Move comments welcome (to clean up document)


Basic model diagram

Basic Model (Diagram)

  • CGN Traffic in IP VPN (BGP/MPLS)

  • Post translated traffic on Global (Internet) routing table

  • Allows separation of legacy IPv4 and CGN IPv4 traffic

  • Utilizes common operation technologies

  • Provides efficient way to accomplish CGN by-pass

  • CGN hardware can be located anywhere on network (no policy routing required)


Dual stack concept with lsn diagram

Dual Stack Concept with LSN (Diagram)

  • Supports dual stack operation if IPv6 is needed with CGN/NAT444


Next steps

Next Steps

  • Further comments welcome

  • Is Document read to progress?

  • When to move to WGLC?
