  5. Cisco’s network elements and I Pv6 Cisco’s network elements and I Pv6 features features • Core Router : Cisco 7600 series • Core Switch : Cisco 6500 series • Firewall : Firewall Services Module (FWSM on 6500) • Access/Aggr/Ref Router : Cisco 7600 series • Man Switch : Cisco 6500 series + IPv6 Addressing 6 Add i + IPv6 Repackaging Cisco IPv6 Cisco IPv6 + IPv6 Switching + IPv6 Switching Features + IPv6 Routing + IPv6 Security + ...

  6. Cisco Cisco 65xx 65xx switches & switches & I Pv6 I Pv6 features features - IPv6 Repackaging - IPv6 Repackaging - IPv6 VPN over MPLS: IPv6 VPN over MPLS (6VPE) Operation - EIGRP for IPv6: OSPF for IPv6 (OSPFv3) and RIP for IPv6 (RIPng) - Encrypting IPv6 Traffic

  8. Technical solutions for IPv6 migration in CPT

  9. Requirements and technical solutions Requirements and technical solutions 1. Requirements : - Do not break the existing structure of the network infrastructure Do not break the existing structure of the network infrastructure - Provide services conveniently and efficiently - Separate IPv6 traffic of each customer Separate IPv6 traffic of each customer 2. Technical solutions proposed : a) Tunnel: 6RD ) T l 6RD b) DualStack: 6VPE

  10. About About 6RD b 6RD Defined in RFC 5969 Tunneling IPv6 through available IPv4 network infrastructure. Includes components: 6RD Boder relay & 6RD resident gateway Includes components: 6RD Boder relay & 6RD resident gateway (CE), tunnel will be created between two network elements: 6RD BR & 6RD RG.

  11. Tunnel Tunnel-6RD Tunnel Tunnel 6RD 6RD solution for 6RD solution for solution for CPT’s solution for CPT s CPT’s Network CPT s Network Network Network

  12. E Evaluate using Tunnel-6RD E Evaluate using Tunnel l l t t i i T T l l 6RD 6RD 6RD - Keep the original network design, deploy IPv6 conveniently - Must to add 6RD Border Relay in core areas use access - Must to add 6RD Border Relay in core areas, use access routers, man switches in each province as 6RD Resident Gateway - Create policies on 6RD BR to separate IPv6 traffic between agencies and departments - The IGR routers is configured IPv6 EBGP to connect to IPv6 network of VNPT

  13. About 6VPE 2001:0420:: 2001:0620:: 2001:0620:: 145.96.0.0 145.95.0.0 MP-iBGP sessions V6 and v4 V6 and v4 6VPE 6VPE 6VPE V6 and V4 2001:0421:: 192.254.10.0 P P V6 and v4 Dual Stack IPv4-IPv6 routers Dual Stack IPv4-IPv6 routers Dual Stack IPv4-IPv6 routers Dual Stack IPv4-IPv6 routers 2001:0621:: P P CE 192.76.10.0 192 76 10 0 V6 and v4 V6 d 4 6VPE 6VPE IPv4 MPLS v4 v4 CE CE • (RFC 2547bis) IPv6 VPN (6VPE) activities similar to IPv4 MPLS VPN • IPv6 packets are sent and received from 6VPE router to 6VPE router via IPv4 LSP’s ( IPv4 Label Switched Path ) • Some notes of 6VPE : - Do not change the MPLS core - Support for IPv4 & IPv6 VPN on the same Interface - C Configure IPv6 VPN similar to IPv4 VPN fi IP 6 VPN i il t IP 4 VPN - IPv6 routing table for each separate customer.

  14. 6VPE 6VPE solution for 6VPE 6VPE solution for solution for CPT’s solution for CPT s CPT’s Network CPT s Network Network Network

  15. E E Evaluate using 6VPE Evaluate using l l t t i i 6VPE VPE VPE - Separate IPv6 traffic of each customer into corresponding VRF - Must to upgrade IOS for all equipment that running DualStack Must to upgrade IOS for all equipment that running DualStack - Enable 6VPE function for PE routers, configure to define the VRF. To connect to internet, It required to add import and export values of the internet VRF to VRF defined - The IGR routers is configured IPv6 EBGP to connect to IPv6 network of VNPT.

  16. Deploying IPv6 testing with CPT Network

  17. Tunnel Test with solution Tunnel Test with solution 6RD Tunnel Test with solution Tunnel Test with solution-6RD 6RD 6RD

  18. S S Some technical issues Some technical issues h i h i l i l i a) Tunnel-6RD: ) T l 6RD - Required to configure, manage and operate a lot of the Tunnels if deployed 6RD IPv6 on the whole network d l d 6RD IP 6 h h l k - The routing table on the 6RD BR will be very large and complex b) 6VPE: - Must to upgrade IOS for all router/switch that be running DualStack + Router 76xx ( >60 ): IOS 12.2SR => IOS 12.2(33)SRB + Switch 65xx ( >20 ): IOS 12.2SX => IOS 12.2(33)SXI

Q4 - Connect to IPv6 network of VNPT from 03 core areas of CPT Q1 network Q2 - Test with 6VPE solution (stage-1) : upgrade IOS for some PE in 2013 0 3 Q3 North area, deploy 6VPE testing and evaluate the results Q4 - Test with 6VPE solution (stage-2) : upgrade IOS for all PE in North Q1 area, deploy 6VPE testing and evaluate the results , p y g Q2 Q2 2014 Q3 - Test with 6VPE solution (stage-3) : upgrade IOS for all Q4 routers/switches that be running DualStack in whole network of CPT, Q1 deploy 6VPE testing and evaluate the results deploy 6VPE testing and evaluate the results Q2 2015 Q3 - Provide IPv6 services Q4 2016 2016 - Completing 2017

  22. Conclusion Conclusion l l i i CPT can provide IPv6 services in future: 1. Internet service 2. Internet value-added services : Web, Mail, DNS ... 3. Virtual private network services (IPv6 -VPN) 4. Audio and video services: Videoconferencing, VoIP, MyTV … 5. Data transmission services 6. 6 D t Datacenter services (hosting, virtualization server ...) t i (h ti i t li ti ) 7. IPv6 services of VNPT 8 8. National/international IPv6 services National/international IPv6 services.
