Hey all,
I'm seeing some weird behavior on a pair of 6509's that I can't
explain. These two 6509/MSFC's are on an ethernet segment with two
other routers that are the DR and BDR. The DR and BDR have formed
adjacencies with the 6509s and with each other, the weird thing is that
the 6509's are
e to have VLANs to do routing/L3 switching, as you
probabaly know. But maybe there's some weird configuration gotcha, specific
to the 6509? Just curious. Thanks.
Larry said the majority of the Cisco campus is networked with L3 switches
and not using vlans. That says a lot right there!

I'd like to add to this something that I haven't seen in other posts yet,
and that is a quick look at layer2 function. I have a Catalyst 6509 with an

VLAN has several secondary addresses assigned to it (I know, not

Actually, you SAY you can use break, but the reference to break in regards
to the config-register means "break while the router is running" which is
very dangerous since anyone with access to the console of the router could
inadvertently pass the break sequence and cause all routing to cease.

I believe the reason for this is the same reason that you can't hook a modem
to your console port. The "Ready-To-Send", and "Clear-To-Send" signals
don't exist on the console port, thus, no flow control. This is the big
physical difference between the console and aux port; the aux port provides
