Command
No Auto-Summary
Use
Disables EIGRP’s default behavior to advertise networks at their classful boundary.
Syntax
Router(config-router)#no auto-summary
Example
In this example, we will disable auto-summary in the EIGRP process and observe the difference. First we will enable EIGRP on all routers for all links.
|
R1(config)#router eigrp 100 |
Notice the EIGRP routes are currently shown at their classful boundaries.
|
R1(config)#do show ip route eigrp |
Now we will type no auto-summary on all routers.
|
R1(config)#router eigrp 100 |
After typing the command, we now see the proper network information.
|
R1(config)#do show ip route eigrp |
