Configure the link
type of a TRILL port.
trill link-type { access [ alone ] |
hybrid | trunk }
By default, the link type of a TRILL port is
access without the alone attribute.
Configuring the DRB priority of a TRILL port
On a broadcast network, TRILL must elect a DRB. An RB with a higher DRB priority is preferred. When two
RBs have the same DRB priority, the RB with a higher MAC address takes precedence.

By default, the DRB priority of a TRILL port is
64.
Setting the link cost for a TRILL port
The link cost of a TRILL port can be automatically calculated by the system or manually set:
•
A manually set link cost takes precedence over a calculated link cost.
•
If no link cost is set and automatic link cost calculation is enabled, the calculated link cost takes
effect.
•
If no link cost is set and automatic link cost calculation is disabled, the default link cost 2000 is
used.
The system automatically calculates the link cost of a TRILL port by using the following formula: link cost
= 20000000000000/interface baud rate.
