• When you set up a TRILL network, avoid the case that multiple TRILL neighbors are established for one RB port, as shown in Figure 4 and Figure 5. { Figure 4 shows a typical network where two TRILL neighbors are established for the same port of an RB. { In Figure 5, because TRILL is not enabled on the port connecting RB2 to RB3, the port will transparently transmit the TRILL Hello frames from RB3. As a result, two TRILL neighbors are established for the port connecting RB1 to RB2. Figure 4 Two TRILL neighbors are established for a port (1) RB 1 Traditional Ethernet switch RB 2 RB 3 TRILL enabled port Figure 5 Two TRILL neighbors are established for a port (2) After you enable TRILL on a port, TRILL can operate correctly by using default settings. A port with TRILL enabled is called a "TRILL port." To enable TRILL: Step 1. Enter system view. 2. Enable TRILL globally and enter TRILL view. 3. Return to system view. 4. Enter Ethernet or aggregate interface view. 5. Enable TRILL on the port. Command system-view trill quit interface interface-type interface-number trill enable Remarks N/A By default, TRILL is disabled globally. N/A N/A By default, TRILL is disabled on a port. 6
