What is ospfExternLSACount?

This reports the number of external (LS type 5) link-state advertisements currently in the router's OSPF link-state database. Admins watch this as a rough gauge of how many external routes (e.g. redistributed BGP or static routes) are being injected into the OSPF domain.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.13.1.6
snmpwalk -v2c -c public <target> RFC1248-MIB::ospfExternLSACount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.13.1.6.1
snmpget -v2c -c public <target> RFC1248-MIB::ospfExternLSACount.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ospfExternLSACount.1
