Hello . I`m from Spain.
I have a problem when I use the OSPFD DAEMON.
I think the topology is correct but I am not sure.
I compiled Zebra with the --enable-multipath=0 option.
I have three PC (A, B,C) with LINUX Red Hat 7.3 , like you can see in the
diagram:
<<...OLE_Obj...>>
The configurations are:
PC A:

The problem is when I tun off two interfaces of one PC, for example:
<<...OLE_Obj...>>
The ospfd works well during 2-3 minutes, but after this the router pass an
INIT DROTHER state.
BLANCO-ospfd# sh ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
RXmtL RqstL DBsmL
0.0.0.1 1 Init/DROther 00:00:08 12.0.0.2
eth3:12.0.0.1 0 0 0
BLANCO-ospfd#
I have change the version of Zebra , but the result is the same.
I `m using quagga-0.96.4.
When the PC B and PC C pass an INIT DROTHER state, they received hello
packets but don`t send it.
They only "see" their directly conections.
In don`t know to resolve the trouble.
Thanks for all.
