• Enable or disable TRILL on all ports in a VLAN, so that the ports in a VLAN have the same TRILL
status (enabled or disabled).
• Do not enable both TRILL and EVB on a port. The allowed VLAN list of a TRILL-enabled port cannot
overlap with that of an EVB-enabled port. For more information about EVB, see EVB Configuration
Guide.
• When you set up a TRILL network, avoid the case that multiple TRILL neighbors are established for
one RB port. When you plan a network, avoid the networks shown in
Figure 5 and Figure 6 .
{
Figure 5 shows a typical network where two TRILL neighbors are established for the same port
of an RB.
{
In Figure 6 , because TRILL is not enabled on the port connecting RB 2 to RB 3, the port will
transparently transmit the TRILL Hello frames from RB 3. As a result, two TRILL neighbors are
established for the port connecting RB 1 to RB 2.
Figure 5 Two TRILL neighbors are established for a port (1)
Figure 6 Two TRILL neighbors are established for a port (2)
