    Description

      1) ODL only accepts BGP connection if 4-byte AS capability is sent by peer
      2) When I enable 4-byte AS support in Spirent it sends the capability along with other capabilities in the same parameter as I show below:

      rame 5: 113 bytes on wire (904 bits), 113 bytes captured (904 bits) Ethernet II, Src: Performa_00:00:05 (00:10:94:00:00:05), Dst: Vmware_ce:72:24 (00:0c:29:ce:72:24) Internet Protocol Version 4, Src: 3.3.3.4 (3.3.3.4), Dst: 3.3.3.3 (3.3.3.3) Transmission Control Protocol, Src Port: 179 (179), Dst Port: 34078 (34078), Seq: 1, Ack: 62, Len: 43 Border Gateway Protocol - OPEN Message
      Marker: ffffffffffffffffffffffffffffffff
      Length: 43
      Type: OPEN Message (1)
      Version: 4
      My AS: 200
      Hold Time: 180
      BGP Identifier: 3.3.3.4 (3.3.3.4)
      Optional Parameters Length: 14
      Optional Parameters
      Optional Parameter: Capability
      Parameter Type: Capability (2)
      Parameter Length: 12
      Capability: Multiprotocol extensions capability
      Type: Multiprotocol extensions capability (1)
      Length: 4
      AFI: IPv4 (1)
      Reserved: 00
      SAFI: Unicast (1)
      Capability: Support for 4-octet AS number capability
      Type: Support for 4-octet AS number capability (65)
      Length: 4
      AS Number: 200

      ODL seems not to like this format because it still complaints about missing 4-byte AS capability where it is clearly there.
