3. IP routing
1. Static routing
ip routing
ip route Target network number Mask Port number [permanent]
2. Default routing
ip default-network network number
3. Dynamic routing
1) RIP configuration
Router rip
Network Number
Show ip route
Show ip protocol
Debug ip
2) OSPF configuration
Router ospf process number
Redisttribute Other routing protocols
Network Port Network Antimask area area number
Area Area range Network number Mask
Area area number default-cost spend value
Ip ospf priority number
Ip ospf cost value
Show ip ospf database
3) BGP configuration
Router bgp Autonomous Domain Number
Redisttribute Other routing protocols
Network network number /* within the autonomous domain */
Aggregate-address Network number Mask summary-only Summary network
Neighbor adjacent network number remote-as autonomous domain number /* network between autonomous domains */
4. Flow control
1) Passive port
passive interface port number
2) Default routing
ip default network number/port network
3) Static routing
ip route target network number mask port number
4) ACL filter table
(Global) access-list access number 1 {permit|deny} antimask number [established]
access-list access number 2 {permit|deny} IP/TCP protocol Source network Destination network
Operator Parameters
(on port) access-group access number in|out
distribute-list access number in|out port number
4） Null 0 interface
