NEW QUESTION 38
A network administrator has recently configured eBGP to use source addressing from its loopback interfaces. Customers later report that eBGP routes are not being learned.
What could be the cause of this issue?

BGP devices must be configured with the multihop command when using loopback interfaces

BGPv4 does not support the use of loopback interfaces

BGP devices must be configured to use source addressing from its physical interfaces only

The network administrator neglected to issue the no shutdown command to bring the loopback interface online
