I was just finishing up my technology specific lab on RIP (IPexpert Volume 1, Lab 8). Step 14 gives the following requirement:

“Routes learned from BB1 that have an odd number in the third octet should be seen with a metric of 10 at R5. The access-list used should contain a single line”

To give you a little backround on the topology, BB1 connects to R1, which connects over ethernet to R2, which connects via frame to R5.

OK…

access-list 5 permit 0.0.1.0 255.255.254.255
router rip
offset-list 5 in 8 e0/0

show ip protocols (supressed output below)
Incoming routes in Ethernet0/0 will have 8 added to metric if on list 5

Now, the very next step in the lab gives this requirement:

“routes in the 64.0.0.0/7 range should not be allowed in your network at all. The access-list should contain a single line”

OK…

access-list 10 permit 64.0.0.0 1.255.255.255
router rip
offset-list 10 in 15 e0/0

show ip protocols (supressed output)
Incoming routes in Ethernet0/0 will have 15 added to metric if on list 10

That’s it! So the moral of the story here is that so far as I can tell you can not apply 2 seperate offset-lists to a single interface in RIP. I suppose to do this task I could just use a distribute-list for the 2nd task.
