Show all possible pathes for specific network in OSPF

There's a loopback on router 4 has an ip 100.100.100.100 , and all routers are running OSPF , 

when I check routes on router1 I got the below

 


100.0.0.0/32 is subnetted, 1 subnets
O 100.100.100.100 [110/2] via 192.168.14.4, 00:28:53, FastEthernet1/0
O 192.168.24.0/24 [110/2] via 192.168.14.4, 00:28:53, FastEthernet1/0
[110/2] via 192.168.12.2, 00:39:36, FastEthernet0/0

 

Its advertised from router 4 as it obviously the best path and less metric

 

I need to see all possibles pathes link we do in EIGRP , i need to see all topology links

 

R1#show ip ospf database

Hi

Try using this command line: show ip ospf route. it should display all the paths to the destinations and their metrics. 

 

Hope it is useful

:-)
