Adding a Secondary LSP to the Trunk

Although the attributes of a Secondary Label Switched Path(LSP) are
independent of the Primary LSP, a Secondary LSP cannot be configured
without first configuring a Primary LSP. Besides information on how to
configure a secondary LSP, this example illustrates how to define non-default
setup and hold priority for an LSP. Setup and hold priorities are used to
determine which LSP should be given a preference when competing for
resources. Specifically the setup priority of an unestablished LSP is compared
to the hold priorities of existing established LSPs and the numerically lower
one is given a preference. However, once the LSP gets established, its setup
priority is never used until it gets pre-empted or reset and is being brought up
again.
