Figure 15-1  Typical Trusted Extensions Routes and Routing Table Entries

• Route #1 can transmit packets within the label range of CONFIDENTIAL to SECRET.

• Route #2 can transmit packets from ADMIN_LOW to ADMIN_HIGH.

• Route #3 does not specify routing information. Therefore, its security attributes are derived from Gateway 5's security template.
