Static Route
- ip route 172.16.0.0 255.255.0.0 e0/0 192.168.12.2
- ip route 0.0.0.0 0.0.0.0 e0/0 192.168.12.2
- ip route 0.0.0.0 0.0.0.0 e0/1 192.168.13.3 10
OSPF (Open Shortest Path First)
- router ospf 1 // router ospf process-id
- interface fastEthernet 0/1
- ip ospf 1 area 0
- ip ospf cost 1
- interface fastEthernet 0/2
- ip ospf 1 area 0
- ip ospf cost 2
- interface vlan 10
- ip ospf 1 area 1
- router ospf 1
- passive-interface vlan 10
- show ip ospf interface brief
- show ip ospf neighbor
- show ip route ospf
- reference-bandwidth (100 Mbps by default)
- router ospf 1
- auto-cost reference-bandwidth 1000 (The reference bandwidth in terms of Mbits per second)
- interface fastEthernet 0/1
- bandwidth 100000 (Bandwidth in kilobits)
- Cost = reference-bandwidth / bandwidth
NAT
- interface Ethernet0
- ip address 192.168.1.1 255.255.255.0
- ip nat inside
- interface Ethernet1
- ip address 211.120.200.2 255.255.255.0
- ip nat outside
- ip nat inside static 192.168.1.100 211.120.200.100
- show ip nat translations
ACL
- FTP (Active Mode)
- access-list 102 permit tcp any host 192.168.1.100 eq ftp
- access-list 102 permit tcp any host 192.168.1.100 eq ftp-data established
- FTP (Passive Mode)
- access-list 102 permit tcp any host 192.168.1.100 eq ftp
- access-list 102 permit tcp any host 192.168.1.100 gt 1024
