Configures the timers associated with the establishment of an LSP.
percent | Specifies a percent increase in the interval allowed before each subsequent attempt to re-signal an LSP. The valid range is from 0 to 100 percent. |
seconds | Specifies the time (in seconds) to wait before attempting to re-signal the LSP. |
retry-limit | Specifies the maximum allowed attempts to establish an LSP. |
number | Specifies a maximum number of allowed attempts to establish an LSP. The valid number range is from zero to 255. |
unlimited | Allows unlimited attempts to establish an LSP. |
Delay interval: 30 seconds.
Decay rate: 0%.
Retry limit: unlimited.
This command configures the timers associated with the establishment of an LSP. If an LSP fails to establish, the LSP is re-signaled based on the configuration of these timers. The delay-interval timer specifies the time (in seconds) to wait before attempting to re-signal the LSP. If the LSP fails to establish itself on subsequent attempts, the delay-interval time is incremented based on the decay-rate setting. The decay operation multiplies the delay-interval time by the decay rate, and adds the result to the current delay-interval time. For example, if the decay-rate is set to 50 percent and the current delay-interval time is 30 seconds, the LSP is re-signaled in 45 seconds. If the LSP failed to establish on the next attempt, the delay interval would be further decayed to 67 seconds.
A per-LSP delay-interval time is maintained for each LSP until the LSP is established. This operation of decaying the retry time continues until the LSP is established or the retry-limit expires. If the retry-limit is reached, attempts to establish the LSP are suspended.
Disabling and enabling the LSP resets the LSP's delay-interval time and retry-limit to the initial configuration settings and LSP establishment attempts resume. The default LSP timer parameter values are 30 seconds for delay-interval, with a 0 percent decay-rate, and retry-limit of unlimited. The valid range for delay-interval is 1 to 60 seconds. The valid decay-rate range is 0 to 100 percent. The valid retry-limit is 0 to 255 or unlimited. A value of 0 indicates that the LSP is not re-signaled.
The following command allows unlimited retries for establishing MPLS RSVP-TE LSPs:
