As per the output above, which of the following is true?

A. RIP updates are sent and received on interface serial 0 of the router

B. A default route is sent to neighbors on interface serial 0 of the router

C. A default route is sent to neighbors on interface ethernet 0 of the
router

D. RIP updates are sent and received on interfaces serial 0 and ethernet 0
of the router

D.
the network 10.0.0.0 only means it is advertising that network, it
doesnt limit the interface it will go out.

Saad,
Normally I would say A only.  That's probably the answer that would be
considered correct.  But I have to qualify that in real life.

I set up router r1 with RIPv1/IOS 12.1(9)  just like your example (int e1 is
substituted for your s1) and made sure the connected routers were able to
ping.

Observed:  RIP only sends/receives updates from the interface covered by the
NET statement.  The default route is not included in any RIP updates.  And
surprise - updates to e0 are generated BUT SUPPRESSED as there aren't any
routes to send (the connected route doesn't need to be sent).

See below.

r1#sh ip route

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

     172.16.0.0/24 is subnetted, 1 subnets
C       172.16.1.0 is directly connected, Ethernet1
     10.0.0.0/24 is subnetted, 1 subnets
C       10.1.1.0 is directly connected, Ethernet0
S*   0.0.0.0/0 is directly connected, Ethernet1

Re: BSCI question


My apologies...correction...  I mis-read answer A.  I don't see any correct
answer.  Is there a "none of the above"?
