This object holds the MD5 password used to authenticate BGP messages exchanged with this specific neighbor, inheriting the peer group's value if the neighbor doesn't have its own configured. Administrators set this to protect a BGP session from spoofed TCP packets or unauthorized peers attempting to inject routes. For example, an engineer sets a unique csBgpNbrMd5Password for a peer connected over a public internet transit link, providing stronger authentication than an unauthenticated session would offer.
