Allocating Bandwidth to an LSP Allocating bandwidth to an LSP lets the LSRs determine how much bandwidth the LSP can consume and how much of the available bandwidth resources can be advertised.
Assigning a Metric to the LSP The user can assign a metric to the LSP, which can be used by routing protocols to determine the relative preference among several LSPs towards a given destination.
Limiting the Number of Hops the LSP Can Traverse By default, the path calculated by CSPF can consist of no more than 255 hops, including the ingress and egress LERs. The user can optionally change this maximum to a lower number.
Configuring the Maximum Packet Size Configuring the maximum packet size allows the user to set a maximum IP packet size for packets that traverse an LSP without being fragmented. It can be configured for both primary and secondary paths.
Enabling a Signaled LSP Enabling the LSP causes the path to be set up and resources reserved on the LSRs in the LSPs primary path.
Disabling a Signaled LSP Disabling a signaled LSP de-activates it, but does not remove the LSP from the device‘s configuration.
