Hi

BGP currently only in global. No one VRF configured in system.

This is my BGP config:

router bgp XXXXX
  bgp router-id XX.XX.XX.15
  bgp always-compare-med
  no bgp default ipv4-unicast
  bgp cluster-id XX.XX.XX.0
  bgp log-neighbor-changes
  neighbor XX.XX.XX.10 remote-as XXXXX
  neighbor XX.XX.XX.10 description XXXXX-GW
  neighbor XX.XX.XX.10 update-source Loopback0
  neighbor XX.XX.XX.14 remote-as XXXXX
  neighbor XX.XX.XX.14 description XXX-GW
  neighbor XX.XX.XX.14 update-source Loopback0
  neighbor XX.XX.225.153 remote-as 3216
  neighbor XX.XX.225.153 description GOLDEN-TELECOM
