Routers are devices that transport packets between networks
equivalent to post offices
routers inspect layer 3 packets based on IP address
routing tables require the routes for the network ID
routers only need Manuel input on routing tables for networks they are not directly connected to
you tell routers what other routers they need to go through to reach a network
routing tables need; network address, subnet mask, next router hop to reach network, which physical interface it uses to reach that router
Need network address to reach network ID
static routers need to account for every network not directly attached to router
static routers are more secure and take less bandwidth
static routes are inside the organization 15-20 routers
each router path is an individual network

if you get "inconsistent address and mask" find the closest free zero, unless you cannot due to other constraints
Routing tables are very helpful when setting up static router connections
edge routers connect networks in different areas rather than interconnect subnetworks in the same area

enable- enables manual on cisco
config terminal- enables configuring on cisco
ip route (network address) (subnet mask)(next hop address)- manually adding to routing table, will let you know if you failed and how
show ip route- shows the connected networks, how they are connected, and the connecting port
exit- backs out of the current setting i.e. leaving the config setting back to normal command inputs
