OSPF no route

[Михаил Хотько]

Hi!

I have some trouble with OSPF:

Switch1 and Switch2 has BIRD on them.

The connections are like that:

<Switch1> gi 0/1 -- gi 0/1 <Cisco> gi 0/2 -- gi 0/1 <Switch2>

Switch1 has:

   - VLAN1 with IP 192.168.0.1/30
   - interface Gi0/1 in access mode and VLAN1
   - OSPF router with network 192.168.0.0/30 area 0.

Switch2 has:

   - VLAN2 with IP 172.16.0.1/24
   - interface Gi0/1 in access mode and VLAN2
   - OSPF router with network 172.16.0.0/24 area 10.

Cisco Switch has:

   - VLAN1 with IP 192.168.0.2/30
   - VLAN2 with IP 172.16.0.2/24
   - interface Gi0/1 in access mode and VLAN1
   - interface Gi0/2 in access mode and VLAN2
   - OSPF router with 2 networks: 192.168.0.0/30 area 0
   - and 172.16.0.0/24 area 10.

The trouble is that Switch1 has not receive route to Switch2, if prefix
length of IP on VLAN1 is 30.
If prefix length is 29 or less everything is OK.
