Transmission error on the switch and need routing help

대응

1.  왼쪽의 토폴로지와 같이 스위치에 주황색 표시등이 켜져 있고 이 표시등이 녹색으로 바뀌고 라우터 간의 통신이 원활하기를 바랍니다.

2. 아래의 라우팅 테이블 중 오른쪽 테이블을 왼쪽 테이블과 동일하게 하고 싶은데 어떻게 해야 하나요?

1. because STP is running, switches automatically blocking redundant links to avoid loops in switching network.

2. you need to configure relevant network to be advertised in OSPF

[moonheesung]

The network is not smooth in the current switch state, so how to solve it? Also, OSPF seems to have a shared connection, how do I solve this?

what you mean by not smooth? you need to add relevent networks to all ospf routers to advertise them.
