A. B. C. D.B
When a router detects a problem with a BGP peering session, it sends a notification message to its neighbor to report the error. The notification message informs the neighbor of the error and provides information about the cause of the problem. The notification message also indicates the reason why the peering session is being terminated.
The action that the local router takes after sending a notification message to a remote peer depends on the type of error that caused the notification to be sent. However, in general, the local router will take one of the following actions:
B. It tears down the TCP session and attempts to re-establish it If the local router detects an error that requires the peering session to be reset, it will tear down the TCP session and attempt to re-establish it. This is typically done when there is a problem with the configuration or capabilities of one of the routers.
A. It begins to send route update information If the local router detects that the peering session has been successfully established, it will begin to send route update information to the remote peer. This is done by advertising the routes that the local router has learned to the remote peer.
C. It waits for the remote router to acknowledge that it is ready to receive routes If the local router detects that the remote peer is not ready to receive routes, it will wait for the remote router to acknowledge that it is ready to receive routes. This is typically done when the remote router has not finished processing the previous route update information.
D. It changes its local state to Established If the local router successfully establishes a peering session with the remote peer, it will change its local state to Established. This indicates that the router is ready to exchange routing information with the remote peer.
In summary, the action that the local router takes after sending a notification message to a remote peer depends on the type of error that caused the notification to be sent. If the error requires the peering session to be reset, the local router will tear down the TCP session and attempt to re-establish it. If the peering session is successfully established, the local router will begin to send route update information to the remote peer and change its local state to Established. If the remote peer is not ready to receive routes, the local router will wait for the remote router to acknowledge that it is ready to receive routes.
