9
smallest value of the maximum number of distribution trees that each RB can compute. From the nickname
list in the LSP advertised by the RB with the highest priority, the first n nicknames comprise the root bridge
list that the local RB uses to compute distribution trees.
To configure the distribution tree parameters:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter TRILL view.
trill N/A
3. Set a priority for the RB.
tree-root priority priority The default setting is 32768.
4. Configure the number of
distribution trees that the RB
wants all RBs to compute.
trees calculate count The default setting is 1.
Enabling logging of TRILL neighbor changes
Perform this task to output logs of TRILL neighbor changes to the configuration terminal.
To enable logging of TRILL neighbor changes:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter TRILL view.
trill N/A
3. Enable logging of TRILL
neighbor changes.
log-peer-change enable
By default, logging of TRILL neighbor changes
is enabled.
Configuring TRILL GR
Graceful Restart (GR) ensures the continuity of packet forwarding when a protocol restarts or an
active/standby switchover occurs. The device on which a protocol restarts or an active/standby
switchover occurs advertises the restart status to the neighbors, and allows the neighbors to re-establish
the neighborship, instead of terminating the connections. GR involves the following roles:
• GR Restarter—Graceful restarting router. It must be GR capable.
• GR Helper—A neighbor of the GR Restarter. It helps the GR Restarter to complete the GR process.
To configure TRILL GR:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter TRILL view.
trill N/A
3. Enable GR for TRILL.
graceful-restart By default, GR is disabled for TRILL.
4. (Optional.) Configure
the GR interval for TRILL.
