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:

advertisement.

Enabling TRILL pseudonode bypass

This feature disables a DRB from generating LSPs for the pseudonode when the DRB has only one
neighbor on a broadcast network. This reduces the number of LSPs in the network.
To enable the pseudonode bypass feature:

Setting the SPF algorithm parameters

The RB uses the SPF algorithm to calculate a shortest path tree with itself as the root based on the
LSDB. The RB uses the shortest path tree to determine the next hop to a destination network. By

Remarks
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.
