It simply becomes another piece of conflicting configuration if it doesn't. If your configuration template doesn't have security configured, but it is required by the auto-discovery advertiser, your implementation would try to open a bgp session and that would fail. Your debugging would show that you received a discovery message, but that tcp fails to connect. The same would be true for GTSM. For BFD, the BGP session may come up, and then bounce, or not proceed into Established. If the parameters are in the discovery message, you don't end up with such mismatches unless you want them to be forced to a particular setting. And even if you have preferences about how the session comes up (e.g. require no authentication for NSR considerations), you still have information in the discovery that permits you to find out why the session may not be establishing. -- Jeff
