Routing Example

An example of routing in the Trusted Solaris environment is shown in the following figure; Figure 3-4 (a) shows the routing diagram and Figure 3-4 (b) shows the routing table. There are three potential routes between Host 1 and Host 2:

• Route #1 is the shortest with a Routing Information Protocol (RIP) metric of 3. Datagrams using route #1 are restricted to a label range of CONFIDENTIAL (C) to SECRET (S).

• Route #2 has a larger label range of ADMIN_LOW to ADMIN_HIGH. Datagrams using route #2 must use have an IP Option set to CIPSO.

• Route #3 has the longest distance of the three routes with an RIP of 6. Its Security Routing Information is unknown, so any security attributes must be derived from the template in tnrhtp for Gateway #5.
