The graphic shows the partial output of the show ip route command:
Refer to the exhibit. What can be concluded about network 192.168.4.0 in the R2 routing table?
- The network was learned through summary LSAs from an ABR.
- The network can be reached through the GigabitEthernet0/0 interface.
- The network was learned from a router within the same area as R2.
- This network should be used to forward traffic toward external networks.
Explanation: In a routing table, a route with the label O indicates a network that is advertised by another router in the same area. In this case, the exit interface is GigabitEthernet0/1. The designation O IA means the entry was learned from an interarea LSA that was generated from an ABR. Label O*E2 indicates an external network. In this case, the network designation of 0.0.0.0/0 indicates that this external network is the default route for all traffic that goes to external networks.
