I have query about BGP active state, please share your expert comments -
From Idle > Connect > Active = Here BGP stuck in "Active" state after connect state due to Source or Destination IP unreacable OR TCP port 179 Not permited/Filter on interface(Used for TCP connection) on either side,
My Under-standing is - This condition in not comes or not relevant due AS no. mismatch, because it all these three state no update message (in which BGP version, As no. information shared) is sharing/traversing by both side.
Please correct me If I am wrong.
2. From Idle > Connect > OpenSent(not received OpenConfirm) > Active = Here BGP stuck in "Active" state due to Update message option not match either side.
My Under-standing is - This condition will not come due to Source or Destination IP unreacable OR TCP port 179 Not permted/Filter on interface(Used for TCP connection) on either side. because these parameter already checks till connect state(TCP 3 way hand shake completed ).
