    R1# show ip route

     - Interfaces must be configured to be in Routing Table
     - C (directly connected)
     - S (Static configured)

    R1# show interfaces
    R1# show interfaces fa0/0

    R1# show interfaces s0/0/0

     - Status
     - IP Address, Subnet Mask




    R1# show ip interface brief

     - Summary of Interfaces
     - IP Address, no Subnet Mask


    R1# show running-config


    R1# debug ip routing

     
    - monitor Router operations in real time


    R1# show cdp neighbors
    R1# show cdp neighbors detail

    R1(config)#
    no cdp run
     
    - globally

    R1(config-if)# no cdp enable
     - CDP in use but no CDP advertisements on particular interface
    ............................................................................................

    Static Routes


    - configured to remote networks not directly connected to Router
    - the command for configuring a static route is ip route.

    R1(config)# ip route net-address subnet mask {ip-address /exit interface}

     - network address (destination network address)
     - subnet mask (remote network to be added, can be summarized networks)
     - ip-address (next hop Router IP address)
     - exit interface (outgoing interface forwards to destination network)

    R1 (config-line)# logging synchronous

     - get rid of unwanted IOS messages

    ..........................................................................................................

    Later, before importing to CLI of each router, Notepad must be edited:

    - add no shutdown to FastEthernet and Serial interfaces
    - replace encrypted text from enable secret with appropriate password
    - removal of mac address command from interfaces
    - removal of ip classless command
    - removal of unused interfaces

    R1(config)# no ip route 192.168.2.0 255.255.255.0 172.16.2.2
     - to delete static route

    R1(config)# ip route 192.168.2.0 255.255.255.255.0 s0/0/0
     - static route using exit interface serial 0/0/0

    R1# show running-config
     - contains current R1 configurations
     - verify static route changes

    ....................................................................................................
    Summary Static Routes
     - Destination Networks summarized into Single Network Address
     - Multiple Static Routes all use same
    Exit-Interface or Next Hop Address

    To implement Summary Route must 1st delete 3 current Static Routes
     R3(config)# no ip route 172.16.1.0 255.255.255.0 s/0/1
     R3(config)# no ip route 172.16.2.0 255.255.255.0 s/0/1
     R3(config)# no ip route 172.16.3.0 255.255.255.0 s/0/1

    Next, configure Summary Static Route
    R3(config)#  ip route 172.16.0.0 255.255.252.0 s0/0/1

    To verify new static route see R3 Routing Table
    R3# show ip route
    ..................................................................................................
    Default Static Route

    - network address (0.0.0.0)
    - subnet mask (0.0.0.0)
    - R1(config)# ip route 0.0.0.0 0.0.0.0 [exit-interface|ip address]

    Iff 3 static routes on R1 & want default static route
     
    - ip route 172.16.1.0 255.255.255.0 s0/0/0
     - ip route 192.168.1.0 255.255.255.0 s0/0/0
     - ip route 192.168.2.0 255.255.255.0 s0/0/0

    Must 1st delete 3 static routes
     
    - R1(config)# no ip route 172.16.1.0 255.255.255.0 s0/0/0
     -
    R1(config)# no ip route 192.168.1.0 255.255.255.0 s0/0/0
     -
    R1(config)# no ip route 192.168.2.0 255.255.255.0 s0/0/0

    Then config single default static route
     -
    R1(config)# ip route 0.0.0.0 0.0.0.0 s0/0/0

    Verify default static route
     -
    R1# show ip route
     -
    S* in Routing Table indicates default static route
