1) I want to know the "daily used IOS commands"
2) I believe that "Show run" and "show ip interface brief"  are ones of them ...
3) I do have little knowledge of Cisco; this is for my personal lab
4) Would you provide the other ones please
5) Thank you

    It really depends on what functions you're running on the router.  Here are some others you might find yourself using regularly:

    show ip route
    show ip ospf neighbors
    show ip bgp
    show ip bgp sum

    If you're running ipsec:

    show crypto isakmp sa
    show crypto ipsec sa

    CBAC or ZBF would have their own commands as well.
