If the ebgp-interface-sensitive command is not configured, the system does not immediately select the sub-optimal route for packet transmission when an interface goes Down. Instead, the system waits for a period of time (defaulting to 180 seconds) before checking whether another interface can be used to send packets to the same destination address. This will interrupt services for a period of time. If the ebgp-interface-sensitive command is run, BGP can quickly detect EBGP link faults and use another interface to establish a BGP peer relationship with the remote peer.

When the interface used for a BGP connection alternates between Up and Down states, running the undo ebgp-interface-sensitive command can prevent the repeated reestablishment and deletion of the BGP session in the event of route flapping. This reduces the use of network bandwidth.

This post is novel in concept, with unique ingenuity, clear passages, different plots, ups and downs, distinct lines, fascinating and fascinating literary skills. It can be described as a word and a classic sentence, which is a model that my generation should learn. I am very interested for this post, which is very helpful to our daily troubleshooting.
