This reply suppriced me! I have tried this severel times, and never seen
this happenes. I just tried in my lab, and this seems to be different in
different versions of IOS!

On an old C4000 running c4000-js-mz.113-11a.bin I get:

router rip
 network 10.0.0.0
 neighbor 10.1.1.10

1w5d: RIP: sending v1 update to 255.255.255.255 via TokenRing0 (10.1.1.1)
1w5d: subnet 10.1.2.0, metric 1
1w5d: RIP: sending v1 update to 10.1.1.10 via TokenRing0 (10.1.1.1)
1w5d: subnet 10.1.2.0, metric 1
1w5d: subnet 10.1.1.0, metric 1

but with c4500-js56i-mz.121-4.bin and the same config I get:

1w5d: RIP: sending v1 update to 255.255.255.255 via TokenRing0 (10.1.1.2)
1w5d: RIP: build update entries
1w5d: subnet 10.1.3.0 metric 1
1w5d: RIP: sending v1 update to 10.1.1.10 via TokenRing0 (10.1.1.2)
1w5d: RIP: build update entries
1w5d: subnet 10.1.3.0 metric 1

Now I think the answer is, hmmmm. I will still refer to section 3 of the
RFC, where it is quite clear you will have to send your entire route
table!
