Routers don't use MAC addresses for routing. They use IP address.
sharing network information between routers
An address that can only be used on the internal network
The routers in the network are operating with consistent routing knowledge.
routers use routing protocols to exchange routing information. check out the link below for lots of information on routing protocols.

Routing protocol is used to dynamically learn routing information so routers know where to send packets. The only other option is to manually define all routers within a network which would be very impractical.
The routing protocol also specifies how routers in a network share information with each other and report changes. The routing protocol enables a network to make dynamic adjustments to its conditions, so routing decisions do not have to be predetermined and static.
Flat routing protocol is a network communication protocol implemented by routers in which all routers are each other's peers. Flat routing protocol distributes routing information to routers that are connected to each other without any organization or segmentation structure between them. Flat routing protocols are primarily those that don't work under a predefined network layout and perimeter. They enable the delivery of packets among routers through any available path without considering network hierarchy, distribution and composition. Flat routing protocol is implemented in flat networks where each router node routinely collects and distributes routing information with its neighboring routers. The entire participating node addressed by flat routing protocol performs an equal role in the overall routing mechanism. Routing Information Protocol, Interior Gateway Routing Protocol and Enhanced Interior Gateway Routing Protocol are popular examples of flat routing protocols.
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.
rip is short for routing information protcol it is a routing protocol that shared routing tables from 1 router to another to a maximum of 16 hops of 16 routers
