Ok yasu, this is the complete topology of my network:
--BACKBONE(10.1.0.0/24)--R0--area1---R1-------VR1------VR5-----area3---VR6--
--
below there are the ospfd.conf files and the zebra status of each routers .
As you can see, routers VR5 and VR6 don't recieve summary LSA of network
10.1.0.0/24
and also VR5 that is an ABR for area3 doesn'e flood any Summary Lsa into
area 1!
thank you for your help!
Daniele

Oggetto: Re: [zebra 22311] ospfd bug?
Would you show us your ospfd.conf ?
I'm now far from my workspace but will check if the problem exist
for my setup when I get back. I checked virtual link 4-5 months ago
and did not find any problem.
regards,
