OSPF VLAN routing problem on PC6248

Hi All,

I have problem with OSPF VLAN routing on PC6248.  There are 3 VLANs- VLAN1, VLAN2 and VLAN4. Routers on VLANs 2and 4 are not neighbours and I can't ping hosts in the 10.10.10.0 subnet (VLAN 2) from 172.30.64.0 subnet (VLAN4) . What I missed?

Here is running config.


console#show running-config

First step would be to check connectivity: can the PowerConnect ping hosts on all three VLANs?

If so, next step is L3 routing: if a host on each VLAN have the PowerConnect set as their "default gateway", can the three ping each other?

Last would be routing protocol: if each VLAN has its own default gateway (not the PowerConnect), then is OSPF adjacency up to the PowerConnect, and if so, are routes learned for the other two VLANs, with correct next-hop?

Thanks for your reply.

 

1. Yes the PowerConnect can ping hosts on all three VLANs.

2. I have no chance to test it right now because it's on a remote site.

3. The routes are learned only for one VLAN4

For Powerconnect I have next

console#show ip ospf neighbor


   Router ID     Priority IP Address      Interface   State            Dead
                                                                       Time
---------------- -------- --------------- ----------- ---------------- ------
172.30.80.26     1        172.30.64.26    vlan 4      Full/BACKUP-DR   30                       - cisco router
192.168.5.2      128      172.30.64.40    vlan 4      Full/DR          35                                 -juniper router

There is no VLAN2 router as a neighbor. I think here is a problem
