"no validate-update-source" is designed when two separate subnets share a
common link (perhaps using unnumbered interfaces, or secondary addresses).
In the requirements he gave, this gives reason to believe a route after its
been received, not to make things up.
So if you and I share a VLAN, yet I use the 11.1.1.0/24 network and you use
the 22.2.2.0/24 network, we won't believe each other's routes once announced
unless we use this command.

Scott,
So what are your thoughts about Victor's suggestion and no
validate-update-source?
I have to confess I have not tested this myself yet - as you can see I'm
currently playing cathcup with gs reading.

You need to actually understand what the network command does, and that will
help answer your question.
The network command in RIP does not announce a route directly. What it does
is activate an interface as "participating" in the RIP process. That in
turn brings the specific route into the RIB and announces it out. However,
following that same logic, in order to activate an interface as
participating, you need to have an interface configured to do so.
You aren't allowed to make things up. But, on the other hand, that's why
(insert Deity-du-jour here) created loopback interfaces! ;)
BGP is similar, but the route must exist in the routing table before it can
be brought into the BGP RIB.
HTH,
Scott

Subject: RIP question
I have playing aroud with RIP on two routers, A and B connected via ethernet
belonging to the same vlan.
I want to see if I can announce a network from router A to B, even though
there is no interface on A belonging to that network.
==========================================
router A
int e0/0
ip addres 192.168.1.1 255.255.255.0
router rip
version 2
no auto-summary
network 192.168.0.0
netwrok 10.10.10.0
==========================================
==========================================
router B
int e0/0
ip addres 192.168.1.2 255.255.255.0
router rip
version 2
no auto-summary
network 192.168.0.0
==========================================
I don't see 10.0.0.0/8 on router B.
I tried introducing a loopback on A belonging to the 10.0.0.0/8 network but
i couldn't see the network on B.
Is there anyway of having rip announcing the 10 network so it shows up on
B's routing table learned via RIP.
