Step Command Remarks
5. Set the TRILL LSP
generation timer
parameters.
timer lsp-generation
maximum-interval
[ minimum-interval
[ incremental-interval ] ]
By default, the maximum LSP generation
interval is 2 seconds, the minimum interval
is 10 milliseconds, and the incremental
interval is 20 milliseconds.
6. Configure the
maximum length of
originated LSPs. lsp-length originate size
The default setting is 1458 bytes.
To prevent the system from generating error
messages, do not set the maximum length of
originated LSPs to be greater than the
maximum length of received LSPs.
7. Configure the
maximum length of
received LSPs.
lsp-length receive size
The default setting is 1492 bytes.
To prevent the system from generating error
messages, do not set the maximum length of
originated LSPs to be greater than the
maximum length of received LSPs.
8. Set the Overload bit of
LSPs and set the lifetime
for the set Overload bit. set overload [ timeout ]
By default, the Overload bit is not set.
Do not perform this task on the root RB of a
TRILL distribution tree. The root RB cannot
forward traffic when the Overload bit of
LSPs is set on the RB.
9. Return to system view. quit N/A
10. Enter Layer 2 Ethernet
or aggregate interface
view.
interface interface-type
interface-number
N/A
11. Configure the minimum
LSP interval and the
maximum number of
LSPs transmitted per
interval.
trill timer lsp interval [ count
count ]
By default, the minimum LSP interval is 10
milliseconds, and the maximum number of
LSPs transmitted per interval is 5.
Enabling TRILL LSP fast advertisement
LSP fast advertisement enables TRILL to immediately advertise the specified number of LSPs that invoke
SPF calculation. This mechanism improves network convergence time.
To enable TRILL LSP fast advertisement:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter TRILL view. trill N/A
3. Enable TRILL LSP
fast advertisement.
flash-flood [ flood-count flooding-count |
max-timer-interval flooding-interval ] * By default, TRILL LSP fast
advertisement is disabled.
