Default IS-IS Configuration
Feature |
Default Setting |
---|---|
Ignore link-state PDU (LSP) errors |
Enabled. |
IS-IS type |
Conventional IS-IS—The router acts as both a Level 1 (station) and a Level 2 (area) router. Multiarea IS-IS—The first instance of the IS-IS routing process is a Level 1-2 router. Remaining instances are Level 1 routers. |
Default-information originate |
Disabled. |
Log IS-IS adjacency state changes. |
Disabled. |
LSP generation throttling timers |
Maximum interval between two consecutive occurrences—5000 milliseconds. Initial LSP generation delay—50 milliseconds. Hold time between the first and second LSP generation—200 milliseconds. |
LSP maximum lifetime (without a refresh) |
1200 seconds (20 minutes) before the LSP packet is deleted. |
LSP refresh interval |
Every 900 seconds (15 minutes). |
Maximum LSP packet size |
1497 bytes. |
NSF Awareness |
Enabled. Allows Layer 3 devicess to continue forwarding packets from a neighboring Nonstop Forwarding-capable router during hardware or software changes. |
Partial route computation (PRC) throttling timers |
Maximum PRC wait interval—5000 milliseconds. Initial PRC calculation delay after a topology change—50 milliseconds. Hold time between the first and second PRC calculation—200 milliseconds. |
Partition avoidance |
Disabled. |
Password |
No area or domain password is defined, and authentication is disabled. |
Set-overload-bit |
Disabled. When enabled, if no arguments are entered, the overload bit is set immediately and remains set until you enter the no set-overload-bit command. |
Shortest path first (SPF) throttling timers |
Maximum interval between consecutive SFPs—5000 milliseconds. Initial SFP calculation after a topology change—200 milliseconds. Hold time between the first and second SFP calculation—50 milliseconds. |
Summary-address |
Disabled. |
