Auto-Summary and No Auto-Summary

Guys I need clarification on this command I am aware it's running by default on a specific routing protocol.

I have a hazy idea on this, but need some clarification on what's the use of it.

    This might be beyond CCNA topic, but is there anyway I can disable fastethernet/ethernet interface from sending/receiving RIP broadcast/multicast or any routing protocols there is.

    Default version control: send version 2, receive version 2
    Interface Send Recv Triggered RIP Key-chain
    FastEthernet0/0 2 2
    Serial0/0 2 2
    Loopback0 2 2
    Loopback33 2 2
    Loopback34 2 2
    Loopback35 2 2

    I am playing with RIP but fastethernet loves to be on the scene sending and receiving routing protocol info.

    2.0.0.0/32 is subnetted, 1 subnets
    R 2.2.2.2 [120/1] via 172.23.24.2, 00:00:15, Serial0/0
    [120/1] via 172.23.23.2, 00:00:28, FastEthernet0/0
    33.0.0.0/32 is subnetted, 1 subnets
    R 33.3.3.3 [120/1] via 172.23.24.3, 00:00:16, Serial0/0
    [120/1] via 172.23.23.3, 00:00:02, FastEthernet0/0
    3.0.0.0/32 is subnetted, 1 subnets
    R 3.3.3.3 [120/1] via 172.23.24.3, 00:00:16, Serial0/0
    [120/1] via 172.23.23.3, 00:00:02, FastEthernet0/0
    55.0.0.0/32 is subnetted, 1 subnets
    R 55.5.5.5 [120/1] via 172.23.24.3, 00:00:16, Serial0/0
    [120/1] via 172.23.23.3, 00:00:02, FastEthernet0/0
    44.0.0.0/32 is subnetted, 1 subnets
    R 44.4.4.4 [120/1] via 172.23.24.3, 00:00:16, Serial0/0
    [120/1] via 172.23.23.3, 00:00:02, FastEthernet0/0

    can you not apply a routing protocol to the interface?

    The routing protocol I had to configure on global conf t mode, not sure if I can enable it per interface.

    All you have done is set the rip version for updates to 2, you have no disabled rip being sent.
    The command "passive-interface" is used to stop sending rip updates, it call be applied to all interfaces or to a specific.The only way to stop the receipt of rip updates is to filter them with an access-list.

    config t
    router rip
    passive-interface default

    I couldn't be bothered to answer the summary question.

    1) Post in the correct forum.
    2) Learn how to use Google.
    3) Learn how to ask a question clearly.

    Thanks for the command, I'll make sure to post on the correct thread next time, so it's all in orderly :) I was trying to search explanation of auto-summary but didn't get so lucky, I will try to search and read more.
