What's the difference between shutting down a neighbor, and clearing the session (hard/soft way)? Don't they both reset BGP neighborship?

Are there specific uses of each methods?

Hello Wassim,

if you use neigh shutdown you are tearing down the session for all the time this command is in your running config.

This allows to keep the configuration of a BGP neighbor for some time instead of deleting the config with no neigh x.x.x.x remote-as


clearing the BGP session is instead a reset of the session but with the will to restart it as soon as possible


Hope to help

Giuseppe
