BGP Neighbor Monitoring in Multi-VRF environment
The core DataSource “BGP-” uses the BGP4-MIB to discover and monitor BGP neighbors on a device. This MIB doesn’t account for VRFs or address families. Does anybody use some advanced DataSources to monitor BGP neighbor state information which considers different VRFs? My use case is: We have some routers with multiple VRFs with overlapping IP subnets (which is obviously the major point of having VRFs...). Hence we do have multiple neighbors with the same neighbor IP within different VRFs. The BGP- DataSource just discovers one neighbor per IP, although there are multiple. I’d like to have a separate instance for each neighbor.
BGP Description
The Datasource BGP- shows per BGP instance a Description based on snmp OID 1.3.6.1.2.1.15.3.1.1 which is the bgp peer identifier. That is not the actual description that's configured in the switch. Here is an example ofBGP configurations. address-family ipv4 vrf t01-WAN bgp router-id 11.226.11.2 network 10.251.0.0 mask 255.255.255.0 network 10.251.1.0 mask 255.255.255.0 network 10.251.2.0 mask 255.255.255.0 neighbor 10.228.3.53 remote-as 65500 neighbor 10.228.3.53 description t01 wan koppeling naar rack z1.3.23 neighbor 10.228.3.53 password *********** neighbor 10.228.3.53 activate neighbor 10.228.3.53 soft-reconfiguration inbound neighbor 10.228.3.53 prefix-list t01-WAN-IP-BLOKKEN out neighbor 10.228.3.53 maximum-prefix 200 50 exit-address-family address-family ipv4 vrf a07-GTT-sip bgp router-id 11.226.11.2 network 10.100.128.16 mask 255.255.255.240 neighbor 10.100.128.1 remote-as 65135 neighbor 10.100.128.1 description a07 gtt euro fiber neighbor 10.100.128.1 password ********* neighbor 10.100.128.1 activate neighbor 10.100.128.1 send-community neighbor 10.100.128.1 prefix-list a07-TO-GTT out exit-address-family A snmpwalk on SNMP OID 1.3.6.1.2.1.15.3 doesn't show the neighbor description. How can we get the bgp neighbor description into the LogicMonitor BGP instance description ?
