I have a issue with the summary address generation in ospf .
The sample network Digaram is attached , As per the diagram R1 and R2 acts as the ABR and would like to genrate a summary route for the area 39 into the backbone are 0 .
I can achieve the same using area range cli . The links between the area 39 and area 0 are WAN links and there is a probablity of it going down .
In such case i would want the respective ABR (either R1 or R2) not advertise the summary address, since the connection to area 39 is not available .
Iam looking at something like a conditional summary advertisement , similar to the conditional default route .
Please let me know if we have an option for the same .
This is a test set up we are doing and we found that when the WAN links are down and one of the routers (R1 or R2) has lost connectivity with area 39 the router advertises the summary address and the packets are dropped since there is no specific routes for area 39.
