Hi all,
Anyone can advice me on this ? There are four dept in our customer network. Each dept has one Cat4507 which connected to the core (Cat6509) via fibre link. There are few LAN connected to each dept. switch including the wireless network. Those LAN are on different vlan/subnet. While those LAN are local to each dept. switch but the wireless network are not. All wireless on every dept are in the same network. How to go about this ? How to configure the backbone in order to make it work ? The backbone itself is on L3.

hi
what u could do
on the 6500 creat a vlan for each dpartment with same vlan number and for wireless vlans as well
and creat on each 6500 SVI for each vlan
enable ip routing between vlans and u can run hsrp to make those two 6500 work in primary and backup
however in this case u need an additional uplink for each 4500 switch so that eac 4500 will have link to each 6500 switch if u cant !!
follow the following example
4500 1
vlan 10
vlan 21 wireless
5400 2
vlan 20
vlan 22
6500 directly connected to those two 4500
interface vlan 10
ip address 192.168.1. 255.255.255.0
no shut
interface vlan 11
ip address 192.170.1.1 255.255.255.0
no shut
interface vlan 20
ip address 192.168.2.1 255.255.0
no shut
interface vlan 22
ip address 192.170.2.1 255.255.255.0
no shut
ip dhcp-exclude address 192.168.1.1
ip dhcp-exclude address 192.170.1.1
ip dhcp-exclude address 192.168.2.1
ip dhcp-exclude address 192.170.2.1
ip dhcp pool vlan10
network 192.168.1.0 /24
defualt-router 192.168.1.1
ip dhcp pool vlan11
network 192.170.1.0 /24
default-router 192.170.1.1
ip dhcp pool vlan20
network 192.168.2.0 /24
defualt-router 192.168.2.1
ip dhcp pool vlan22
network 192.170.2.0 /24
default-router 192.170.2.1
and configure the link between the 4500 and 6500 as trunk link
also put this command on accessports on 4500
on the interface config
spanning-tree portfast
and on this 6500 do:
spanning-tree root primary vlan 10,11,20,22
do the same idea on the other side between the 4500 and 6500 enable IP routing for exampel on this 6500
router eigrp 1
no auto-summary
network 192.168.1.0
network 192.168.2.0
network 192.170.1.0 0.0.0.255
network 192.168.2.0 0.0.0.255
the same idea on the other 6500
if u do the link between the two 6500 as layer two link just make trunk and thats it
if u make it layer three link with IPs then u need to add this link network IP to the eigrp as well
good luck
