某网络连接形如：HostAGE00MSR1S10S10MSR2GE00HostBbr两台MSR路由器MSR1、MSR2通过各自的S10接口背靠背互连，各自的GigabitEthernet00接口分别连接客户端主机HostA和HostB。通过配置IP地址和路由目前网络中HostA可以和HostB实现互通。如今在MSR2上增加了如下配置：brfirewallenablebraclnumber3000brrule0denytcpdestinationporteqtelnetbrinterfaceSerial10brlinkprotocolpppbripaddress1.1.1.2255.255.255.252brfirewallpacketfilter3000inboundbrfirewallpacketfilter3000outboundbrinterfaceGigabitEthernet00bripaddress10.1.1.1255.255.255.0br那么如下哪些说法是正确的？br
A.后配置的firewallpacket-filter3000outbound会取代firewallpacket-filter3000inbound命令<br/> B.在HostB上无法成功Telnet到MSR-1上 C.在HostB上可以成功Telnet到MSR-1上 D.最后配置的firewallpacket-filter3000outbound不会取代firewallpacket-filter3000inbound命令正确答案BD
