BGP default route into OSPF Area 0

Hello,

 

Our Scenarios is two routers connected to ISP 1 and ISP2 both learning default route via BGP.

 

We have further single router attached to each ISP 1 and ISP 2 accordingly and then these two routers are connected via P2P. The idea is to redistribute BGP routes into OSPF area 0 so when one of the ISP links are down traffic is re routed via P2P link to 2nd ISP. 

 

It's working absolutely fine but I the LAN routers 1 and 2 are only showing default coming from ISPs then connected to not via P2P link. I know the routing table won't show more than one default route but is there a way to check whether default route is also learned via P2P link ?

 

If I do sh ip ospf route on one of the P2P link routers it would show 

 


External Route List
*> 0.0.0.0/0, Ext2, cost 1, fwd cost 1, tag 1
via 8.2.1.1, GigabitEthernet0/0/1

First Hop Forwarding Gateway Tree

8.2.1.1 on GigabitEthernet0/0/1, count 2
8.2.1.2 on GigabitEthernet0/0/1, count 1
8.2.1.3 on BDI10, count 2
8.2.1.4 on BDI10, count 1

 

 

We have done default orginate on both ISP routers so default is injected into ospf ..

 

Please can you guide.

Hello.

 

'show ip ospf database' should show you both default routes...
