RTRT  415  489  499很多题目都相同但是答案有所不同
英语不是很好  很多题目一道道看有点伤脑筋

诸如99题
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.

415答案为A 489答案为C
根据题意得知BGP配置没有问题,中间存在Firewall,很有可能deny了tcp  179 所以这题是选A  ?!
