6.3.2 show ip route ospf
This command is used to verify the OSPF entries in the Routing Information Base (RIB). Entries with multiple
paths shown are used with ECMP. The two server networks in this example, 10.60.1.0 and 172.16.1.0, each
have two paths from Z9100-Spine1, one through each leaf switch.
The first set of routes with a subnet mask of /32 are the IPs configured for router IDs.

S4148F-Leaf1 has two paths to all other leaf switches and two paths to Server 2’s network, 10.60.1.0. There
is one path through each spine switch.
