Inherited Network - Cisco 4506 Config Question

I've inherited a network that has a VoIP VLAN and a Data VLAN (as well as a SonicWall Firewall).  Currently the SonicWALL is handling the Routing between the VLANs and it sucks...  I've posted up my configuration for the Cisco 4506 because I'm sure it can be configured more optimally but I just don't know what to change.  Any assistance would be great!!

Well, you are right for trying to moving the routing to the switch.

Your first step would be to do this at night and make sure you have backups of your current configurations.

What are the IP's on the SonicWall? All you really have to do is disable the routing on the sonicwall and enable a routing protocol on the switch such as eigrp (and provide the nextworks)

10.2.2.1 is the IP on the SonicWALL  10.2.2.2 is the Cisco IP and 10.3.2.1 is the VoIP IP

what i would do, it make the cisco switch have the IPs, 10.2.2.1, 10.1.2.1 and 10.3.2.1.

So you what have the scheme like this

Sonicwall(10.1.2.2)-------Switch(10.1.2.1, 10.2.2.1, 10.3.2.1)------LAN(10.2.2.X)
                                                                       |
                                                                         Voice(10.3.2.x)

You would configure your switch to use eigrp and have a default gateway of 10.1.2.2.

It would similar to:

router eigrp 10
   network 10.1.2.0
   network 10.2.2.0
   network 10.3.2.0
   no auto-summary

ip route 0.0.0.0 0.0.0.0 10.2.2.2

Which interface would I give the 10.1.2.1 address?  The port going to the SonicWall?

All three (10.1.2.1, 10.2.2.1, and 10.3.2.1) would be on the switch as vlans. the 10.1.2.2 would be sonice wall.


that last line should be ip route 0.0.0.0 0.0.0.0 10.1.2.2

If you are not really familar with Cisco I would consider hiring someone to do this unless you are sure you can revert back if it doesnt work

I'm pretty comfortable with Cisco devices.  It's the Sonic wall and the VoIP system that frighten me (anything to save a buck it seems before I inherited it).  I just don't want to break anything beyond repair but the previous guy jacked a lot of stuff up so I'm trying to rebuild things.  Thanks for all your help though!!  I'm awarding points now as there will be a little time before I can implement anything (3 or 4 weeks) but again, thanks!

In that case, take screen shots of everything just in case it doesnt work! You should be fine though.
