The P4S company's external routers BGP peer with multiple service providers and external organizations. In all situations, the external routers are peered with their BGP neighbors through directly-connected interfaces. How does GTSM provide additional security for your BGP speakers?
A) GTSM prevents the processing of BGP packets from devices that are not on the directly-connected interfaces.
B) GTSM replaces the TCP 3-way handshake between BGP speakers on directly connected interfaces.
C) GTSM prevents random TCP resets from being injected into the BGP data stream.
D) GTSM prevents the formation of BGP adjacencies from unauthorized devices.

GTSM (Generalized TTL Security Mechanism) provides security by ensuring that BGP packets are only processed if they have a TTL value that indicates they are from directly-connected interfaces, thus preventing packets from devices that are not directly connected.
