ospfv3ExtAreaLsdbLimit

Module: OSPFV3-MIB

OID (symbolic): OSPFV3-MIB::ospfv3ExtAreaLsdbLimit

OID (numeric): 1.3.6.1.2.1.191.1.1.11

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: The maximum number of non-default AS-external-LSA entries that can be stored in the link state database. If the value is -1, then there is no limit.

When the number of non-default AS-external-LSAs in a router's link state database reaches ospfv3ExtAreaLsdbLimit, the router enters Overflow state. The router never holds more than ospfv3ExtAreaLsdbLimit non-default AS-external-LSAs in its database. ospfv3ExtAreaLsdbLimit MUST be set identically in all routers attached to the OSPFv3 backbone and/or any regular OSPFv3 area (i.e., OSPFv3 stub areas and not-so-stubby-areas (NSSAs) are excluded).

This object is persistent, and when written, the entity SHOULD save the change to non-volatile storage.

What is ospfv3ExtAreaLsdbLimit?

The maximum number of non-default AS-External LSAs this router will hold before entering database Overflow state (a protective mode that stops originating more external routes); -1 means unlimited. This value must match across every router in the backbone and any regular area, and is commonly used to protect low-memory routers from an external-route flood.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.191.1.1.11
snmpwalk -v2c -c public <target> OSPFV3-MIB::ospfv3ExtAreaLsdbLimit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.191.1.1.11.1
snmpget -v2c -c public <target> OSPFV3-MIB::ospfv3ExtAreaLsdbLimit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.191.1.1.11.1 i <value>
