Successor routes are going to be in the routing table since they are the best path to a remote network. However, the topology table has a link to each and every network, so the best answer is topology table and routing table. Any secondary route to a remote network is considered a feasible successor, and those routes are found only in the topology table and used as backup routes in case of primary route failure.

At the moment of OSPF process startup, the highest IP address on any active interface will be the Router ID (RID) of the router . If you have a loopback interface configured (logical interface), then that will override the interface IP address and become the RID of the router automatically.

The four routed protocols supported by EIGRP are IP, IPv6, IPX, and AppleTalk.

When you connect to a switch port, at first the link lights are orange/amber, and then they turn green, indicating normal operation. If the  link light is blinking, you have a problem.

Debug ip rip is used to show the internet Protocol (IP) Routng Information protocol (RIP) updates being sent and received on the router.
