Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correct BGP session endpoint addresses and the correct BGP session hop-count limit （EBGP multihop）. What is a good first test to see if BGP will work across the firewall？（）
A
Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the outside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transport data.
B
Ping from the router connected to the inside interface of the firewall to the router connected to the outside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP to transport packets.
C
There is no way to make BGP work across a firewall without special configuration， so there is no simple test that will show you if BGP will work or not， other than trying to start the peering session.
D
There is no way to make BGP work across a firewall.
