Enabling Logging Of Trill Neighbor Changes - HP 6125XLG Trill Configuration Manual

Compute TRILL distribution trees according to the LSDB.
•
• Use the TRILL distribution trees to guide the forwarding of multicast, broadcast, and unknown
unicast frames.
An RB with a higher priority is selected as the root bridge of a TRILL distribution tree.
An LSP carries TRILL distribution tree information that includes the following:
The number of TRILL distribution trees that the RB wants all RBs to compute.
•
The maximum number of TRILL distribution trees that the RB can compute (this number is fixed at 15).
•
The number of TRILL distribution trees that the RB has computed.
•
An RB determines the number of TRILL distribution trees to compute (n) by selecting the lower value from
the following two values:
The number of TRILL distribution trees that the highest-priority RB wants all RBs to compute.
•
The smallest value of the maximum number of TRILL 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 TRILL distribution trees.
When multicast ECMP is disabled, traffic can be load shared because the topologies of TRILL distribution
trees are different. However, equal-cost links are not used for load sharing. When multicast ECMP is
enabled, TRILL can assign equal-cost links to different TRILL distribution trees. This improves the load
sharing performance.
To configure the TRILL distribution trees:
Step
1. Enter system view.
2. Enter TRILL view.
3. Set a priority for the RB.
4. Configure the number of
TRILL distribution trees that
the RB wants all RBs to
compute.
5. Enable multicast ECMP.

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:
Command
system-view
trill
tree-root priority priority
trees calculate count
multicast-ecmp enable
14
Remarks
N/A
N/A
The default setting is 32768.
The default setting is 1.
By default, multicast ECMP is
disabled.
Make sure the multicast ECMP
status is the same on all RBs in the
TRILL network. Otherwise,
multicast, broadcast, and
unknown unicast frames might
fail to be forwarded.
