Simulation Attributes
The following simulation attributes are available (Configure/Run Discrete Event Simulation dialog box) when using the MPLS model suite.
•CR-LDPRouting—specifies if CR-LDP routing uses CSPF or conventional IGP to determine routes in loosely defined LSPs. The default value is IGP.
•CSPF Retry Timer—specifies how long an ingress LER waits after detecting a node or link failure before rerouting an LSP that traverses the failed node or link. The default value for this attribute is 45 seconds.
•LDP Discovery End Time—specifies when LDP discovery ends. After this time, no more LDP discovery packets are sent through the network. This value should occur after the network reaches a final, constant state in the simulation since no network topology or device status changes are reflected in the LDP routing tables after LDP Discovery End Time.
•LDP Discovery Start Time—specifies when LDP starts sending discovery packets through the network. Set this attribute to a value other than Do Not Start to enable LDP.
•LSP Signaling Protocol—specifies whether dynamic LSPs are signaled using CR-LDP (constraint-based routed LDP) or RSVP. The default value is CR-LDP.
