You work as a network engineer for the company， you want to configure two BGP speakers to form an EBGP session across a firewall. On the engineer’s network， the firewall always permits TCP sessions that are initiated from the inside network （the network attached to the inside interface of the firewall）. What prerequisite is there for enabling BGP to run on this network？（）A、EBGP multihop will need to be configured for this to work.B、This should work with normal BGP peering， with no additional configuration on the BGP speakers or the firewall.C、The BGP protocol port must be opened on the firewallD、There is no way to make BGP work across a firewall.
