Network Issues

With RTR Version 3, two network transports are available:

DECnet (default on OpenVMS)

TCP/IP

At least one transport is required. If a destination supports both transports, RTR Version 3 can use either.

Any node can run either protocol, but the appropriate transport software must be running on that node. For example, for a node to use the DECnet protocol, the node must be running DECnet software. (For specific software network version numbers, see the RTR Version 3 OpenVMS Software Product Description.)

A link can fail over to either transport within RTR. Sufficient redundancy in the RTR configuration provides greater flexibility to change transports for a given link when necessary.

4.1 DECnet Support

With RTR Version 2, the only transport was DECnet Phase IV; it provided DECnet Phase V support but without longnames. With RTR Version 3, both DECnet Phase IV and DECnet-Plus (DECnet/OSI or DECnet Phase V) are supported, including support for longnames and long addresses.

4.2 TCP/IP Support

DECnet-Plus and TCP/IP provide multihoming capability: a multihomed IP node can have more than one IP address. RTR does name lookups and name address translations, as appropriate, using a name server. To use multihomed and TCP/IP addresses, Compaq recommends that you have a local name server that provides the names and addresses for all RTR nodes. The local name server should be available and responsive.

Name servers for all nodes used by RTR should contain the node names and addresses of all RTR nodes. Local RTR name databases must be consistent.

Note

Include all possible addresses of nodes used by RTR, even those addresses not actually used by RTR. For example, a node may have two addresses, but RTR uses only one. Include both addresses in the local name database.
