Overview of TCP/IP Routing

This section describes TCP/IP routing on ClearPath MCP servers. TCP/IP initializes in dual mode and can support both the IPv4 and IPv6 protocols running simultaneously on a ClearPath server. This section describes the basic routing concepts shared by IPv4 and IPv6 and explains the new features supported by IPv6 to enhance TCP/IP routing capabilities.

Notes:
  • The IP addresses shown in the sample topologies in this section are for reference only. Do not use these addresses.

  • If a routing feature is supported on both IPv4 and IPv6 networks, the sample topologies that illustrate the feature assume dual-mode operation and show support for both IPv4 and IPv6 running simultaneously. Therefore, both IPv4 addresses and IPv6 addresses are shown in the topologies, but these addresses cannot be intermixed. That is, a node with an IPv4 address cannot communicate with another node that has an IPv6 address.
