Commands to View OSPF Routes

CD

The correct answers to view OSPF routes are C. show route protocol ospf and D. show route.

C. show route protocol ospf: This command is used to view the routes learned via OSPF protocol. When this command is executed, it displays the routes that are learned via OSPF and their attributes such as destination prefix, next-hop, protocol preference, and metric.

Example:

sqlCopy code
user@router> show route protocol ospf   inet.0: 13 destinations, 13 routes (13 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both  10.0.0.0/8        *[OSPF/10] 01:58:49, metric 1                       to 10.1.1.2 via ge-0/0/1.0 

D. show route: This command is used to display the routing table. It shows all the routes installed in the routing table, including OSPF routes, as well as routes learned via other routing protocols or static routes.

Example:

sqlCopy code
user@router> show route   inet.0: 13 destinations, 13 routes (13 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both  10.0.0.0/8        *[OSPF/10] 01:58:49, metric 1                       to 10.1.1.2 via ge-0/0/1.0  192.168.1.0/24    *[Direct/0] 02:15:05                       > via ge-0/0/0.0  224.0.0.0/4       *[Multicast/10] 02:15:15                       MultiRecv  

Option A, "show ip route ospf", is not a valid Junos command. The Junos command to display the routes learned via OSPF is "show route protocol ospf".

Option B, "show ospf routes", is not a valid Junos command. The Junos command to display the OSPF routes is "show route protocol ospf".
