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***
      |                      |
    WB                 WB
    /|\                    /|\
   / | \                  / | \

 /   |  \                /  |   \

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?

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 ?.

You have a duplicate for

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.
