We need to configure a standard IPV4 ACL to restrict access to PINK LAN

1. Access list 10 remark ACL_TO_PINK_LAN
2. Permit PC-C to reach the PINK LAN

Enter configuration commands, one per line. End with CNTL/Z.

R2(config)#access-list 10 remark ACT_TO_PINK_LAN
R2(config)#access-list 10 permit 192.168.2.50

3. Permit only the half of the host on YELLO LAN

R2(config)#access-list 10 permit 172.16.1.0 0.0.0.127
R2(config)#no access-list 10 permit 172.16.1.0 0.0.0.127

R2(config)#access-list 10 permit 192.168.1.0 0.0.0.127
