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.
What is the BGP synchronization rule？（）A、Routing information received through an IBGP session is not forwarded to another IBGP neighbor， onlyto EBGP neighborsB、Routing information received through an EBGP session is not forwarded to another EBGP neighbor，only to IBGP neighborsC、BGP neighbor peerings are established and sychronized using the TCP 3-way handshakeD、BGP shall not advertise a route until that route has been learned via an IGP also
