Configuring Trill Gr; Associating A Trill Port With A Track Entry - HP 5920 Series Configuration Manual

Step
1. Enter system view.
2. Enter Layer 2 Ethernet or
aggregate interface
view.
3. Configure the link type of
the port as trunk.
4. Enable EVB.
5. Enable TRILL to forward
traffic from EVB
S-channels.

Configuring TRILL GR

Graceful Restart (GR) ensures the continuity of packet forwarding when a protocol restarts or an
active/standby switchover occurs on the RB. The RB advertises the restart status to its neighbors, and
allows the neighbors to re-establish 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.
•
By default, the device acts as the GR helper. Configure TRILL GR on the target GR restarter.
To configure TRILL GR:
Step
1. Enter system view.
2. Enter TRILL view.
3. Enable GR for TRILL.
4. (Optional.) Configure
the GR interval for TRILL.
5. (Optional.) Suppress the
SA bit during graceful
restart.

Associating a TRILL port with a track entry

Associate a track entry with a TRILL port to fast detect the loss of connectivity to the neighbor on the port.
Track can collaborate with Connectivity Fault Detection (CFD) to monitor the link state of the neighbor.
For more information about CFD and Track, see High Availability Configuration Guide.
To use CFD to detect link failures in a TRILL network, you must configure the outward-facing MEPs. CFD
supports only single-hop detection. CFD packets cannot be forwarded by RBs.

The default link type of a port is access.
By default, EVB is disabled on a port.
By default, TRILL does not support forwarding
traffic from EVB S-channels.
The trill evb-support command and TRILL
commands (including trill enable) are
mutually exclusive. Do not configure both EVB
and TRILL on an interface.

By default, GR is disabled for TRILL.
The default setting is 300 seconds.
By default, the SA bit is set during graceful
restart.
