Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4.5.8
snmpwalk -v2c -c public <target> BSDUNIX-MIB::unixRouteLookupFails

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4.5.8.1
snmpget -v2c -c public <target> BSDUNIX-MIB::unixRouteLookupFails.1
