Most monitoring products allow you to monitor custom SNMP OIDs, and your entire BGP RIB is – usually – exposed via SNMP. Most monitoring products also treat “missing” OIDs specially, and can alert on that fact. At least, that’s how I would start doing it. We use Observium here, and it can do what you want, albeit with a little bit of futzing around in the Custom OID and Alerts sections.
Cisco does weird things with getting SNMP data from VRFs, though, so… YMMV. I know there used to be a Cisco-proprietary way to select which VRF you were polling common OIDs from, but don’t remember the details. -Adam Adam Thompson Consultant, Infrastructure Services [MERLIN] 100 - 135 Innovation Drive Winnipeg, MB, R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) athomp...@merlin.mb.ca<mailto:athomp...@merlin.mb.ca> www.merlin.mb.ca<http://www.merlin.mb.ca/> From: NANOG <nanog-bounces+athompson=merlin.mb...@nanog.org> On Behalf Of Sandoiu Mihai Sent: Thursday, January 6, 2022 4:35 AM To: nanog@nanog.org Subject: BGP Route Monitoring Hi I am looking for a route monitoring product that does the following: -checks if a specific bgp route from a specific neighbor is present the BGP table (in some vrf, not necessarily internet routed vrf) of an ASR9K running IOS XR -sends a syslog message or an alarm if the route goes missing The use case is the following: we are receiving same routes over 2 or more bgp peerings, due to best route we cannot really see at the moment if one of the routes ceased to be received over a certain peering. Alternative approach: a product that measures the number of bgp received prefixes from a certain peer. Do you know of such product that is readily available and does not require ssh sessions to the routers and parsing the outputs? I am trying to find a solution that does not require much scripting or customization. Many thanks. Regards Mihai
