One more thing. You will have to ask the proctor on this one. I was told
not to correct it!!!
When you create a summary route in RIP on the router creating the summary
route you must add a static route for that summary address to Null0.
Every other routing protocol does this by default but RIP will NOT. If you
traceroute to a address that would fall into the summary range and not in
one of the more specific routes you will see a serious routing loop.

R1---R2
R1
interface FastEthernet3
ip address 10.0.0.2 255.255.255.0
router rip
version 1
network 10.0.0.0
R2
interface Loopback0
ip address 10.10.0.1 255.255.255.252
interface Ethernet0/0
ip address 10.0.0.1 255.255.255.0
ip summary-address rip 10.10.0.0 255.255.255.0
router rip
version 1
network 10.0.0.0
10.10.0.0/30 route would normally not make it to R1 since same major net as
interface, but
different mask. With summary-address command (for RIPv1) we can summarize to
same mask as
interface and route appears:
R1#i r
10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks
R 10.10.0.0/24 [120/1] via 10.0.0.1, 00:00:04, FastEthernet3

I think it does. RIP V1 is classfull so you'd use this command to send
summaries that
match the interface mask into the RIP network from a router that is also
running OSFP or
any other classless protocol and redistributing routes into RIP. I'll lab
it up and let
you know.

Correct me if I am wrong but this command has no effect with V1 ?
