Question
User101 can not access R7/R8, fix this problem so that User101 can ping loopback 0 of R7.
Ensure the output is the same as show below when User101 traceroute Server1 (3 hops)

User101#traceroute 172.16.200.200
Type escape sequence to abort.
Tracing the route to 172.16.200.200

2. 172.16.1.21 0 msec 1 msec 0 msec
3 .172.16.200.200 1 msec * 1 msec

mac 이 server int와 R7의 설정과 다를때는 어느 mac을 우선시?
스위치에 sticky 있는데 그대로 user 서버에 mac으로 바꿔넣어도되나
switchport port-security mac-address sticky
switchport port-security mac-address sticky aabb.cc00.3300

=================
static check
User101#show ip route
Gateway of last resort is not set

dhcp ip check
User101#show ip interface brief
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 unassigned YES DHCP up up

dhcp interface check
User101#show running-config | include dhcp
ip address dhcp client-id Ethernet0/0 hostname User101

=> dhcp 설정은 있는데 e0/0에 ip가 할당이 안되서 unassigned 되었군
=>

pc로 부터 ip를 broadcast로 요청받는 기능 확인
[x] SW2#show running-config | include dhcp
SW2#show running-config | include helper
