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
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

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.

Lessons to learn:
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.
