Strategy for Coexistence With Conventional TCP/IP
•
Special considerations apply for the ND6HOSTD process. See Managing the
ND6HOSTD Process on page 6-18.
•
You can add up to 64 SUBNETs to an LNP because you can only have 64
SUBNETs in the NonStop TCP/IPv6 subsystem, if you have 64 SUBNETs in one
LNP, the default LNP only has the loopback interface. At the other extreme, you
can have 64 LNPs, each with one SUBNET.
Strategy for Coexistence With Conventional
TCP/IP
To provide the features that are unsupported by NonStop TCP/IPv6, the conventional
TCP/IP environment is present with the restriction that you cannot share the same IP
SUBNET address (LIF) between environments.
Conventional TCP/IP allows a fallback position as well as providing the unsupported
features.
Falling Back to Conventional TCP/IP or Parallel
Library TCP/IP
This subsection provides fallback procedures for returning your system to use either
conventional TCP/IP or Parallel Library TCP/IP. In addition to reading these
procedures, see Managing the System Configuration Database on page 6-14.
Note. For the same application processes, one socket can be associated with the
conventional NonStop TCP/IP subsystem and another socket simultaneously associated with
the NonStop TCP/IPv6 subsystem.
