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

When N equal-cost links exist in the network, each TRILL distribution tree selects an equal-cost link for
forwarding packets through J mod N in root bridge priority order. J is the priority sequence number of a
multicast tree and starts from 0.
As shown in
The link directly connecting RB 1 to RB 3 is assigned to the TRILL distribution tree rooted at RB 3.
•
The link RB 1-RB 2-RB 3 is assigned to the TRILL distribution tree rooted at RB 4.
•
To configure the distribution trees:
Step
1. Enter system view.
2. Enter TRILL view.
3. Set a priority for the RB.
4. Configure the number of
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:
Step
1. Enter system view.
2. Enter TRILL view.
3. Enable logging of TRILL
neighbor changes.

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.

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.
