Description:
  <neighbor-id>         Peers

Identifiers:
  <vrf-id>              VRF (vrf-name)
  <neighbor-id>         Peer ID (ipv4 | ipv6 | interface-name)

Attributes:
  address-family        Address family specific configuration
  bfd                   Specifies whether to track BGP peering sessions using thisconfiguration via BFD.
  capabilities          Capabilities
  description           neighbor description
  enable                Turn the feature 'on' or 'off'.  This feature is enabled by default.
  enforce-first-as      If on, when BGP updates are received from EBGP peers with this config, check that first AS matches peer's AS
  graceful-restart      BGP Graceful restart per neighbor configuration
  local-as              Local AS feature
  multihop-ttl          Maximum hops allowed.  When 'auto', the type of peer will determine the appropriate value (255 for iBGP and 1 for eBGP).  This is the default.
  nexthop-connected-check
                        If 'on', it disables the check that a non-multihop EBGP peer should be directly connected and only announce connected next hops
  passive-mode          If enabled, do not initiate the BGP connection but wait for incoming connection
  password              Password
  peer-group            Optional peer-group to which the peer is attached to inherit the group's configuration.
  remote-as             ASN for the BGP neighbor(s) using this configuration.  If specified as 'external', it means an EBGP configuration but the actual ASN is immaterial. If specified as 'internal', it means an IBGP configuration.
  shutdown              Administratively shut down this neighbor
  timers                Peer peer-timerss
  ttl-security          RFC 5082
  type                  The type of peer
  update-source         Source of routing updates
