It's a theoretical question. So far I've had one person email me saying
OSPF can advertise a subnet as local on a shared multi-access media. If
in fact BGP can't do this, then it's no big deal to me as nothing in my
network relies on this functionality.

If you are going through all this trouble, why not just secondary the

Are you just asking a question to get a better understanding of how
things work, Ralph or have you already put this into production and are

My understanding is the route is valid as long as the interface is
up; just like adding a secondary IP on the interface.

Aha.
So, if you route to a ethernet interface, it will try to arp for that
address on that subnet, even without having a local address on the same
subnet?
This seems to me to be something you don't want to do.
Is the entire route valid as long as the router can ARP for one of the
addresses in

OK, I'll bite.
I've been doing ip route statements going on 8 years now, and I can't
imagine why ever -- and how it would even work -- you'd want to ip route a
netblock with a next hop of a multi-access brandcast media. As in, the
next hop is still truly undetermined.
I guess I don't know this

Ralph,
What you are asking for is dynamic routing protocol to be able to tell you
how to do something locally scoped. This is why we have redirects on
ethernets. But, since you must do this with BGP, try this... (I haven't)

Well, Corning had to do something with all that extra fiber they
couldn't sell, so they make a gigantic spool and made it a light buffer.

As others are saying... it isn't "local". It's not "local"
unless in the same subnet. Physical topol
Really, the only way this could happen is if Router B is not announcing its
routes to 172.16.16/24 and Router A has a default route to its Ethernet
interface.

Hi there,
What really confuses the heck out of me is that a company this size can't
control/monitor their change management??. Then again not having all the
facts has had everyone perplexed.

No its not possible to say you can reach the subnet on the same media...
IP maps to the [Ethernet] with ARP, but before a packet is passed down to MAC
via ARP it is routed and if there is no route to the connected ethernet then it
will necessarily need to use the other router.
You must have th

A and B are connected via the same multi-access media. It is technically
possible for B to tell A "you can reach 172.16.16.0/24 on the same media
that you receive this update on". However what people seem to be saying
is that there is no dynamic routing protocol that implements this.

Can you create another segment with 172.16.16? May be another dotq1q
interface?.

I've already had several direct replies saying to manually configure the
172.16 subnet on router A. Sure, that will work, but I'm looking for a

Background:
Router A and B are connected via a common ethernet segment 1. Router A
uses 10.10.10.1/30, and Router B uses 10.10.10.2/30. Router B also has
another subnet configured for ethernet segment 1; 172.16.16.0/24.
When I setup a situation like the above, with Router B advertising the
172.
