`bgp`, as defined at https://oidref.com/1.3.6.1.2.1.15, is missing the following properties;
- `bgpLocalAs` (https://oidref.com/1.3.6.1.2.1.15.2)
- `bgpIdentifier` (https://oidref.com/1.3.6.1.2.1.15.4)
- `bgpPeerInUpdateElapsedTime` (https://oidref.com/1.3.6.1.2.1.15.3.1.24)
- `bgpPeerFsmEstablishedTime` (https://oidref.com/1.3.6.1.2.1.15.3.1.16); this one should indicate how long (in seconds) this peer has been in the Established state or how long since this peer was last in the Established state.
After a reboot, all the BGP sessions are established at almost the same timestamp (+/- 10 minutes ago), side-by-side the output of `snmpwalk` '.1.3.6.1.2.1.15.3.1.16' is shown. 10 minutes should result in 600 seconds, these values are far off and quite random;
