a VPN for a few sites and I'm testing how to get traffic from an ATM cloud
through our switched network as seen below. In theory, it should be Layer 2
all the way from the CPE to the Test Machine.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=298522904-21042008>I can confirm that
t</SPAN></FONT><FONT face=Arial size=2><SPAN class=298522904-21042008>he Layer 2

<DIV><FONT face=Arial size=2><SPAN class=298522904-21042008>I can also confirm
that the Layer 2 between the Test Machine to Interface Gig0/0.903 is
working. Similarly, <SPAN class=298522904-21042008>I put an IP address on each

<DIV><FONT face=Arial size=2><SPAN class=298522904-21042008>So my questoin is -
can ATM and Ethenet co-exist by putting them both into the same bridge group as
seen in the config above such that the CPE which is connected to the ATM cloud
is able to reach the test machine which is attached to the ethernet
sub-interface on vlan 903 through the use of this bridge
group?</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=298522904-21042008>If this is not
possible, are there alternatives to what I want to do?</SPAN></FONT></DIV>
