Hello. I am nearing the end of my CCNA 2 class, and I am on the routing concepts chapter.
This image was on part of the module, and I cannot for the life of me interpret what it is trying to tell me. It has no key to go along with what the numbers mean.
I understand that they are entrys on the routing table, and from what I can tell it is the output you might get from the command
R1# show IP route.
I apologize if similar questions have been asked before, or if this is a silly question with a really obvious answer, but I am not really sure what to search to get an answer on how to interpret this image. Thank you for the help

this routing table entry indicates that traffic destined for the
10.0.4.0/24 network
should be sent to the next-hop
IP address 10.0.3.2
via the Serial0/1/1 interface, using a OSPF routing protocol with a metric of 110 and a cost of 50. The entry was last updated 13 minutes, and 29 seconds ago.
its same logic for IPv4 or IPv6

"Metric of 110 (This has not been discussed in my class, i am not sure what this means)"
- no, this is administrative distance, in short AD, it tells how believable is this route based on Cisco pre-defined scale of connected, static routes and routing protocols (see scale map ). Any static routes have AD of 1 and are better then OSPF AD 110, Lower number is better, all directly connected routes are the best with AD of 0
Yes, 4- Cost or metric 50 - this is OSFP cost or metric for this route/network at this router.
5 and 7 tells u how to reach that network, what is next hop IP or exit interface.
in short, network xyz is OSPF route with cost 50 that you can reach via x IP or via serial interface xyx

Thank you! If I am understanding this right,
1- OSPF routing protocol
2- Designates what traffic it will route
3- Metric of 110 (This has not been discussed in my class, i am not sure what this means)
4- Cost of 50 (Also has not been discussed)
5- Next hop destination for the traffic designated in 2
6- When the entry was last updated
7- The interface that this route is routing on
