Configuring The Drb Priority Of A Trill Port; Setting The Link Cost For A Trill Port - HP 6125XLG Trill Configuration Manual

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.
To configure the DRB priority of a TRILL port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet or
aggregate interface
view.
3. Configure the DRB
priority of a TRILL port.

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.
To set the link cost for a TRILL port:
Step
1. Enter system view.
2. Enter TRILL view.
3. Enable automatic link cost
calculation for TRILL ports.
4. Return to system view.
5. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
6. Configure the link cost for a
TRILL port.
