BGP SNMP v3 vs. v2c

Hello,

Over the past few years I have posted issues about BGP alerts and BGP with Cisco IOS-XR on ASR’s and NCS routers.

Here are my posts from before -

SNMP polling on Cisco NCS

Hello, I have posted for the past couple years about librenms not reporting, alerting, on BGP sessions on cisco routers with IOS-XR. So i have a few cycles and started to look into things more. First i dug into the mib using - Cisco MIB browser i found the MIB - BGP4-MIB, assuming that is the MIB librenms is using, i located the spot on where in the MIB it is looking for the state - bgpPeerState OBJECT-TYPE SYNTAX INTEGER { …

BGP Alert Notification Status on Cisco NCS-57C3-MODS-SYS

So i hate to beat a dead horse on this. With my original post of - That was on and still is on a Cisco ASR9006 and the issue is still happening. Now i have started to move my Cisco ASR9001 to Cisco NCS-57C3-MODS-SYS the issues has happening where all the BGP sessions say “state” Could it be my alert rule? my rule for down is - bgpPeers.bgpPeerState != “established” AND macros.device_up = 1 my rule for establised is - %bgpPeers.bgpPeerFsmEstablishedTime < “300” && %bgpPeers.bgpPeerStat…

Cisco ASR 9006 BGP status

If you run that SQL query within mysql, what is in the bgpPeers.bgpPeerState column?

I finally solved the issue. I switched Librenms from polling the routers at SNMPv3 to SNMPv2c and poof i have all my sessions back and their states.

Developers, What data would you like from me help solve why polling works with v2 and not v3 for BGP states.

Thanks in advance,

Howdy Community,

Any thoughts on why BGP stats and information works flawless with SNMP v2 and not v3?

Best,
