NO.180 A network connection is like:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
The two MSR routers MSR1 and MSR2 are interconnected back-to-back through their S1/0 interfaces, and their GigabitEthernet0/0 interfaces are respectively connected to the client hosts HostA and HostB. HostA can communicate with HostB in the current network by configuring the IP address and routing.
The following configuration has been added to MSR-2:
firewall enable
acl number 3000
rule 0 deny tcp destination-port eq telnet
interface Serial1/0
link-protocol ppp
ip address 1.1.1.2 255.255.255.252
firewall packet-filter 3000 inbound
firewall packet-filter 3000 outbound
interface GigabitEthernet0/0
ip address 10.1.1.1 255.255.255.0

NO.181 The customer’s network connection looks like:
HostA—-GE0/0–MSR-1–S1/0—–WAN—-S1/0–MSR-2–GE0/0—-HostB
The customer’s WAN network only supports synchronization, and S1/0 of MSR-2 needs to negotiate an IP address from the opposite MSR-1 instead of manually configuring a static IP address.
Then the S1/0 interface of the two routers can run ______. (Multiple choice)

NO.182 The customer’s network connection looks like:
HostA—-GE0/0–MSR-1–S1/0—–WAN—–S1/0–MSR-2–GE0/0—-HostB
