Question 1:
You're configuring an OSPF ASBR, and have determined that all the routes injected into OSPF via redistribution can be summarized with the address 23.0.0.0 /12.
What is the full OSPF command to advertise this summary into the OSPF domain in place of the specific routes?
Question 2:
You're performing two-way route redistribution between an EIGRP AS and an OSPF domain. On the OSPF routers, what is the default routing table code for the routes learned from EIGRP?
Extra credit: What code will appear on the EIGRP routers next to any routes that are injected into the EIGRP AS from OSPF?
Consider the following OSPF configuration and answer the following questions.
R4(config)#router ospf 1
R4(config-router)#network 172.12.0.0 0.0.0.255 area 0
R4(config-router)#network 1.1.1.1 0.0.0.0 area 1
R4(config-router)#router-id 20.1.1.1
< router reloaded at this point >
R4(config)#interface loopback0
R4(config-if)#ip address 50.1.1.1 255.255.255.255
Question 3:
Is that a legal configuration? If not, why not?
Question 4:
What is the OSPF process number?
Question 5:
What is the RID of this particular router?
Question 6:
Is this router an ABR, ASBR, both, or neither?
Explain why this router is or isn't an ABR.
Explain why this router is or isn't an ASBR.
This ends the questions about that router configuration.
Question 7:
An OSPF total stub router can contain what route types?
A. Default route only
B. E2 routes and a default route
C. E1 routes and a default route
D. Intra-area routes and a default route
E. Inter-area routes and a default route

Answers:
1. The full command is:
summary-address 23.0.0.0 255.240.0.0
2. These routes will appear as OSPF External Type 2 routes and will have a router table code of "O E2".
The routes that are redistributed from OSPF into EIGRP will appear in the EIGRP routing tables with a code of "D EX".
3. Yep, it's legal.
4. The OSPF process number is 1, as indicated by the router ospf 1 command.
5. The OSPF RID was hardcoded as 20.1.1.1, and it took effect after the router reload I mentioned.
6. This router is an ABR since it borders Area 1 and Area 0.
There is no route redistribution shown on this router, so it's not an ASBR.
7. "D". The routing table of a total stub router can contain intra-area routes and a default inter-area route using the ABR as the next hop.
