Chapter 39 Remote Loop-Free Alternate - Fast Reroute
How to Configure Remote Loop-Free Alternate - Fast Reroute
Step 9
max-lsp-lifetime
seconds
Example:
Router(config-router)#
max-lsp-lifetime 65535
Configures the maximum link-state packets (LSPs) lifetime.
• seconds—Maximum LSP lifetime in seconds. The range is from
1 to 65535.
Step 10
lsp-refresh-interval
seconds
Example:
Router(config-router)#
lsp-refresh-interval 900
Sets the link-state packet (LSP) refresh interval.
• seconds—Interval (in seconds) at which LSPs are
refreshed.The range is 1 to 65535 seconds. The default value is
900 seconds (15 minutes).
Step 11
spf-interval [level-1 | level-2]
spf-max-wait [spf-initial-wait
spf-second-wait]
Example:
Router(config-router)# spf-interval 5
50 200
Customizes IS-IS throttling of shortest path first (SPF) calculations.
• level-1—(Optional) Apply intervals to Level-1 areas only.
• level-2—(Optional) Apply intervals to Level-2 areas only.
• spf-max-wait—Indicates the maximum interval (in seconds)
between two consecutive SPF calculations. The range is 1 to
120 seconds. The default is 10 seconds.
• spf-initial-wait—(Optional) Indicates the initial SPF
calculation delay (in milliseconds) after a topology change. The
range is 1 to 120000 milliseconds. The default is 5500
milliseconds (5.5 seconds).
• spf-second-wait—(Optional) Indicates the hold time between
the first and second SPF calculation (in milliseconds). The
range is 1 to 120000 milliseconds. The default is 5500
milliseconds (5.5 seconds).
Step 12
prc-interval prc-max-wait
[
prc-initial-wait prc-second-wait
]
Example:
Router(config-router)# prc-interval 5
50 200
Customizes IS-IS throttling of partial route calculations (PRC).
• prc-max-wait—Indicates the maximum interval (in seconds)
between two consecutive PRC calculations. Value range is 1 to
120 seconds. The default is 5 seconds.
• prc-initial-wait—(Optional) Indicates the initial PRC
calculation delay (in milliseconds) after a topology change. The
range is 1 to 120,000 milliseconds. The default is 2000
milliseconds.
• prc-second-wait—(Optional) Indicates the hold time between
the first and second PRC calculation (in milliseconds). The
range is 1 to 120,000 milliseconds. The default is 5000
milliseconds (5 seconds).
