| Description |
|---|
| If the same passwords are used between eBGP neighbors, the chance of a hacker compromising any of the BGP sessions increases. It is possible that a malicious user exists in one autonomous system who would know the password used for the eBGP session. This user would then be able to hijack BGP sessions with other trusted neighbors. |
