2. Load Sharing (pages 109-112) Can be equal cost or unequal-cost
Load sharing can be:
per destination (fast switching), or
per packet (process switch)
ASIC vs CPU

3. OSPF Router Types Internal Rtr - all interfaces in single area
Backbone Rtr – at least 1 interface in area 0
Area Border Router – has interfaces in multiple areas
Autonomous System Border Router – act as gateways between OSPF and other routing protocols

8. In Quito, Lima, etc. no need to run OSPF
Example for Quito router
ip route
In M1, for Quito LAN, add a static route
ip route
In M1 (and M2) add to OSPF routing statements
Router OSPF 50
redistribute static subnets
redistribute connected subnets

9. OSPF redistribute Lots of options
Protocol type (static, RIP, EIGRP, etc.)
Metric
Metric-type
Route-map
Subnets (do this almost always)

10. OSPF Virtual Link Connect 2 areas without using area 0
Must be configured between ABRs
Transit area must have full routes
You must know the Router ID of end points
