IPv6 Backbone Network Solution

IPv6 Backbone Network Solution

This section describes the IPv6 backbone network solution.

Figure 5-4 shows how the NE40E is applied on an IPv6 backbone network.

Figure 5-4 Application of the NE40E on an IPv6 backbone network

When IPv4 and IPv6 coexist on the backbone network, IPv4 forwarding or MPLS VPN can be used to ensure that existing IPv4 services are not affected. In addition, the following requirements must be met:

  • Interconnection between separate IPv6 networks
  • Interworking between IPv6 and IPv4 networks

To meet the preceding requirements, NE5000Es, and NE40Es can work together to provide the following solutions:

  • All routers on the backbone network support the IPv4/IPv6 dual stack. IPv4 services are forwarded using IPv4, and IPv6 services are forwarded using IPv6.
  • The separate IPv6 networks are interconnected over 6to4 or manually configured Layer 3 tunnels. The core routers only need to support IPv4 forwarding and do not need to be upgraded.
  • The separate IPv6 networks are interconnected over MPLS L2VPN connections, such as VPLS or CCC connections. The core routers only need to support MPLS forwarding. The interworking between IPv6 and IPv4 networks is implemented by configuring NAT-PT on gateways.
