[j-nsp] potential bug in SNMP engine on JunOS 13.3R6.5

[Drew Weaver]

Howdy,

I am trying to monitor the status of a BGP session that has no prefixes using SNMP:

admin at MX80> show bgp summary

169.254.255.57         xxxx      81677      87595       0      10     3w6d11h 1/1/1/0              0/0/0/0

if I snmpwalk 1.3.6.1.2.1.15.3 (notice the timeout at the end)

[root at linuxweb html]# snmpwalk -v2c -c yyyy xxxx 1.3.6.1.2.1.15.3
SNMPv2-SMI::mib-2.15.3.1.1.169.254.255.1 = IpAddress: 169.254.255.1

SNMPv2-SMI::mib-2.15.3.1.5.169.254.255.57 = IpAddress: 169.254.255.58
Timeout: No Response from yyyy

if I snmpwalk the specific OID I need:

[root at linuxweb html]# snmpwalk -v2c -c xxxx yyyy 1.3.6.1.2.1.15.3.1.7
SNMPv2-SMI::mib-2.15.3.1.7.169.254.255.1 = IpAddress: 169.254.255.1
SNMPv2-SMI::mib-2.15.3.1.7.169.254.255.57 = IpAddress: 169.254.255.57
Timeout: No Response from yyyy

Anyone know a way around this? the BGP session with no prefixes is a backup tunnel and the prefixes will only activate when the primary goes offline. I would still like to monitor the bgp session between the two devices however.

Thanks.
