 ### BGP: frr_bgp_peer_types_up
 FRR Exporter exposes a special metric, `frr_bgp_peer_types_up`, that can be used in scenarios where you want to create Prometheus queries that can report on the number of types of BGP peers that are currently established, such as for Alert Manager. To implement this metric, a JSON formatted description with a 'type' element must be configured on your BGP group. FRR Exporter will then aggregate all BGP peers that are currently established and configured with that type.
 
 For example, if you want to know how many BGP peers are currently established that provide internet, you'd set the description of all BGP groups that provide internet to `{"type":"internet"}` and query Prometheus with `frr_bgp_peer_types_up{type="internet"})`. Going further, if you want to create an alert when the number of established BGP peers that provide internet is 1 or less, you'd use `sum(frr_bgp_peer_types_up{type="internet"}) <= 1`.
 
-To enable `frr_bgp_peer_types_up`, use the `--collector.bgp.peer-types` flag.
