Description Ted Kaczmarek 2003-01-06 23:34:44 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030104

Description of problem:
Route will not install if cipe interface ip is in same address space.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Bring up cipe inteface on HOST A with ip of 192.168.200.1 and HOST B peer of
192.168.200.2
2.Have bgp peer HOST A send 192.168.0.0/16 route to HOST B
3.Confirm route in bgp table, not in kernel routing table
    

Actual Results:  Route of 192.168.0.0/16 is not put in kernel routing table.

Expected Results:  Route of 192.168.0.0/16 is put into kernel routing table.

Additional info:

As a test instead of sending the /16 which overlaps the cipe interface, I sent
it as a /17, that route does get put into the kernel routing table. Wasn't sure
if this is kernel or cipe, but it is definelty cipe related. I even advertised
the same route from another peer (Router C)across the ethernet0 and saw the same
issue.

Will attach a diagram as well.

This problem does not occur with 2.4.18-24.8.0, no point in leaving this open.
