When I Issue The "show Ip Route Bgp" Command, I See My Routes Being Learned Via Ospf And Bgp. How Can I Verify On The Nx-os Which One Will Always Be Used And Which One Is A Backup?

Here is what is received:

  1. Nexus_7010#show ip route bgp
  2. IP Route Table for VRF "default"
  3. '*' DENOTES BEST ucast next-hop
  4. '**' denotes best mcast next-hop
  5. '[x/y]' denotes [preference/metric]

 

  1. 172.20.62.0/23, ubest/mbest: 1/0
  2. *via 10.194.160.2, [20/0], 18:53:35, bgp-[AS-Number], INTERNAL, tag [Number]
  3. via 10.194.16.5, Vlan116, [110/1043], 18:43:51, ospf-1, intra
  4. 172.20.122.0/23, ubest/mbest: 1/0
  5. *via 10.194.160.2, [20/0], 18:53:35, bgp-[AS-Number], internal, tag [Number]
  6. via 10.194.16.5, Vlan116, [110/1041], 18:43:51, ospf-1, intra

By default, BGP selects only a single best path and does not perform LOAD balancing. As a result, the route marked with the * will always be used, unless it goes down, at which point any remaining routes will become the preferred path.
