many folks on the list have asked me, off list, to clarify what I am
trying to do/what situation I am in. I think this lays it out.
The 7200 has this:
ip route 216.10.32.0 255.255.224.0 FastEthernet0/0
ip route 216.10.32.0 255.255.255.0 216.10.46.2
ip route 216.10.33.0 255.255.255.0 216.10.46.2
ip route 216.10.36.0 255.255.255.0 216.10.32.10
ip route 216.10.37.0 255.255.255.0 216.10.46.2
ip route 216.10.46.0 255.255.255.0 FastEthernet0/0
ip route 216.10.47.0 255.255.255.0 216.10.46.2
ip route 216.10.62.0 255.255.255.0 216.10.46.2
ip route 216.10.63.0 255.255.255.0 216.10.46.2
The 3640 has this:
ip route 0.0.0.0 0.0.0.0 216.10.46.1
ip route 216.10.32.0 255.255.255.0 FastEthernet2/0
ip route 216.10.33.0 255.255.255.0 FastEthernet2/0
ip route 216.10.37.0 255.255.255.0 FastEthernet2/0
ip route 216.10.46.0 255.255.255.0 FastEthernet1/0
ip route 216.10.47.0 255.255.255.0 FastEthernet2/1
ip route 216.10.62.0 255.255.255.0 Ethernet0/0
ip route 216.10.63.0 255.255.255.0 FastEthernet2/1
Explanation as far as I understand it:
Right now:
The 7200 points 216.10.32.0 /19 to it's Ethernet interface.
It also points 216.10.32.0 /24 to the 3640 via 216.10.46.2
It also points 216.10.33.0 /24 to the 3640 via 216.10.46.2
The means that the 7200 receives packets from the WAN links and spits
them directly at client machines on ethernet.*
The client machines then respond to the 3640 as it is addressed with
their gateway (ie 216.10.32.1).
and/or
It spits packets to the 3640 and the 3640 routes the packets to the
correct interface and all is well.
(the above ala round robin routing/load-balancing)
The above troubles me as I want to DIRECTLY point 216.10.32.0 /24 and
216.10.33.0 /24 to the 3640 Using Ethernet but not broadcasting it to
the world.
But! When I remove the 216.10.32.0 /19 route from the 7200 I get nothing!
When I remove the route 216.10.32.0 /19 am I seeing arp tables being
rebuilt and I am to impatient/scared to continue? If I wait will
things begin to move correctly?
Thanks all for putting up with me on this one!
*The ethernet network currently connects all of the ethernet ports on
all of the routers to each other and the clients (don't ask.. I am
cleaning as we speak!)
