need help with point-multipoint loadsharing with ospf - HP5800 comware 5
I'm trying to setup something similar to Cisco CEF on HP5800 switch. That will utilise both links.
Someone said the same can be achieved with equal cost loadbalancing with ospf and I have 2 point-point links loadshared with OSPF with 2 physical interfaces on HP5800 switch.
Now I have new pair of point-multipoint links and only 2 free ports on 5800.
Need to know if the following scenario would work properly.
192.168.10.0/24

***HP5800***

a1 b1 c1 a2 b2 c2
a1&a2 wireless bridges belong to same site and have a cisco router for OSPF, likewise the same pattern is followed for other locations, office wireless bridges (WB) are terminated to HP5800. And have put the interfaces to "port link-mode route" and created multiple sub ip addresses.
OSPF process 1(existing point-point links i've mentioned earlier) running with router id 2.2.2.2 and router type is ASBR.
ospf 2 default-route-advertise maximum load-balancing 2 maximum-routes external 8 area 1.1.1.1 network 10.0.22.8 0.0.0.3 network 10.0.22.12 0.0.0.3 network 192.168.10.0 0.0.0.255
When i create second ospf and add network on HP5800, it says "Warning: OSPF Network is already in another process".
ospf 3 default-route-advertise maximum load-balancing 2 maximum-routes external 8 area 2.2.2.2 network 10.0.22.16 0.0.0.3 network 10.0.22.20 0.0.0.3 network 192.168.10.0 0.0.0.255
Am I doing this wrong or Is there a better way to achieve the results ?.
Thanks.

Eby,
If i'm looking at your requirements correctly, may be better off looking at a LACP/etherchannel solution rather than OSPF.
Does your Cisco router support LACP?

Pete

Re: need help with point-multipoint loadsharing with ospf - HP5800 comware 5
Thanks Pete,
I'm not sure if LACP is the right solution for this. I have 2 wireless bridges(ISP provided, not sure if these are L2) per site, 3 sites in total and only 2 bridges(ISP) where 5800 is located.
Apart from this, need to keep all sites in separate network.
Can you explain why we were geting that OSPF "Warning" message on HP5800 ? Is it OSPF or comware5 limitation ?.
Regards,
Eby

Re: need help with point-multipoint loadsharing with ospf - HP5800 comware 5
What i want to understand is,
1, Aren't we allowed to advertise same networks multiple times over different ospf areas(other than area 0) ?. If we are, why is it giving "Warning"/duplicate message.
2, Whether it will do load sharing regardless of "Warning" message.
3, Is there a better way to achieve loadsharing using existing devices.
Regards,
Eby
