complete LSDB because of insufficient memory, routing calculation errors occur. To make
troubleshooting easier, temporarily exclude the RB from the TRILL network by setting the Overload
bit for the LSPs sent by the failed RB.
• Minimum LSP interval and maximum number of LSPs transmitted per time—To avoid frequent LSP
aging in the network, RBs periodically advertise LSPs. The actual refresh interval of an LSP is
determined by both the minimum LSP interval and the maximum number of LSPs transmitted per time.
To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh
interval appropriately.
To adjust LSP-related parameters:
Step
1. Enter system view.
2. Enter TRILL view.
3. Set the LSP maximum
age.
4. Set the LSP refresh
interval.
5. Configure the
maximum length of an
LSP originated by an
RB.
6. Configure the
maximum length of an
LSP that can be
received by an RB.
7. Set the Overload bit of
LSPs and set the lifetime
for the set Overload bit.
8. Return to system view.
9. Enter Layer 2 Ethernet
or aggregate interface
view.
10. Configure the minimum
LSP interval and the
maximum number of
LSPs transmitted per
time.

The default setting is 1200 seconds.
The default setting is 900 seconds.
The default setting is 1458 bytes.
The maximum length of an LSP originated
by an RB cannot be greater than the
maximum length of an LSP that can be
received by an RB. Otherwise, the system
displays error messages.
The default setting is 1492 bytes.
The maximum length of an LSP that can be
received by an RB cannot be smaller than
the maximum length of an LSP originated by
an RB. Otherwise, the system displays error
messages.
By default, the Overload bit is not set.
Do not set the Overload bit for LSPs sent by
the root bridge of a TRILL distribution tree.
Otherwise, the traffic to be forwarded
through the RB cannot be forwarded.

By default, the minimum LSP interval is 10
milliseconds, and the maximum number of
LSPs transmitted per time is 5.
