Routing Example

An example of routing in the Trusted Solaris environment is shown below. Figure 3-4 shows the routing diagram and shows the routing table. There are three potential routes between Host 1 and Host 2.

Figure 3-4 Typical Trusted Solaris Routes and Routing Table

• 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 broader label range of ADMIN_LOW to ADMIN_HIGH. Datagrams using route #2 must 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.
