<DIV dir=ltr><FONT face=Arial color=#000000 size=2>1. if your router is
"Max out" why not route the vlan's at a layer 3 switch. your going to have
better through put anyway. If your simply routing vlan's this can be done
at wire speed in hardware with a switch. let a router interface your PSTN
and bigger routing protocols ie. BGP</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>2. Seperating out into more vlan's
gives you more options to secure and protect. Good Idea.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>3. Less host per subnet equals less
arp and better performance.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>They are telling you right.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>So tell management your doing it for Better
performance, Security, and reliablity. That makes my management buy off
;-)</FONT></DIV>

cisco-voip@puck.nether.net<BR><B>Subject:</B> [cisco-voip] Network Change
Recommendations<BR></FONT><BR></DIV>
<DIV>
<DIV>We have some engineers in helping with a new callmanager and IPCC
implementation at a secondary company of ours.</DIV>
<DIV> </DIV>
<DIV>They have made some recommendations on some network changes and I wanted to
ask others about the changes and what you think would be the pro's and con's of
doing so and why do you think they are suggesting these changes. </DIV>
<DIV> </DIV>
<DIV>1. Move the inter-VLAN routing to the switches. (This office
has a maxed out 3845 acting as the core router and voice gateway, it currently
does all routing)</DIV>
<DIV> </DIV>
<DIV>2. Seperate VLANs for servers, pc's, callmanagers, phones
(Currently we have one vlan for servers and pc's, and one VLAN for callmanagers
and phones)</DIV>
<DIV> </DIV>
<DIV>3. Remove class B addressing and utilize Class C addressing (The
internal network was originally configured with Class B addressing
throughout)</DIV>
<DIV> </DIV>
<DIV>Thats the bigger changes that I really just want to understand the various
pro's for why they would recommend them. They make sense and I don't
question that these are not best practices but I want to really understand why
the changes to sell it to management. Their philosophy is "if its not
broke dont fix it" and feel that the network has been working fine so why all
the changes. </DIV>
<DIV> </DIV>
<DIV>Thanks for your time!</DIV></DIV></BODY></HTML>
