TTL = 1 can be normal,sharing an example

Hi,

eBGP (external BGP) by default requires two devices to be directly connected to each other in order to establish a neighbor adjacency. This is because eBGP routers use a TTL of one for their BGP packets. When the BGP neighbor is more than one hop away, the TTL will decrement to 0 and it will be discarded.

The first check that the device will perform is the directly connected route in his routing table, if He doesn't have this route it won't even try to stablish the TCP connection.
