Description Daniel Senie 2002-08-09 18:37:22 UTC

Description of Problem:

The initscripts are placing a separate default route in the kernel routing 
table for each address in a range. These routes are all identical and 
redundant. This was not the case with RedHat 7.0. Example output of netstat -nr:

How Reproducible:

100%

Steps to Reproduce:
1. add a range of IP addresses (in my case, on same subnet as base interface)
2. reboot or restart networking
3. netstat -nr

Actual Results:


Expected Results:

Expected only a single default route, since that is quite sufficient.

This should be fixed in the current rawhide initscripts (6.88-1, or later).
