R211x-HP Flexfabric 11900 TRILL Configuration Guide

8
To configure the link type of a TRILL port:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2 Ethernet
or aggregate
interface view.
interface interface-type
interface-number
N/A
3. 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.
To configure the DRB priority of a TRILL port:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Layer 2 Ethernet or
aggregate interface
view.
interface interface-type
interface-number
N/A
3. Configure the DRB
priority of a TRILL port.
trill drb-priority priority
By default, the DRB priority of a TRILL port is
64.
Configuring the link cost for a TRILL port
The link cost of a TRILL port can be automatically calculated by the system or manually configured:
• When a link cost is manually configured, the manually configured link cost takes effect regardless
of whether automatic link cost calculation is enabled.
• When a link cost is not manually configured and automatic link cost calculation is enabled, the
automatically calculated link cost takes effect.
• When a link cost is not manually configured and automatic link cost calculation is not enabled, 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 configure the link cost for a TRILL port:
Step Command Remarks
1. Enter system view.
