Which Command do you enter so that R1 advertises the loopback0 interface to the BGP Peers?
A. Network 172.16.1.32 mask 255.255.255.224
B. Network 172.16.1.0 0.0.0.255
C. Network 172.16.1.32 255.255.255.224
D. Network 172.16.1.33 mask 255.255.255.224
E. Network 172.16.1.32 mask 0.0.0.31
F. Network 172.16.1.32 0.0.0.31

I’m thinking it’s ok. BGP advertises only network from routing table. it’s A
A is the correct answer.

Let’s create a loopback interface with a network and advertise it in BGP:
R1(config)#interface loopback 1
R1(config-if)#ip address 1.1.1.1 255.255.255.0
R1(config)#router bgp 1
R1(config-router)#network 1.1.1.0 mask 255.255.255.0
Above we have created a loopback interface with network 1.1.1.0 /24, this is what we will advertise in BGP.
