3com 4800G & HP network

[arachna]

This is my first post :)

Ok here it is.I am having problem with inter vlan routing in my network.The core switch is 3com 4800g and other switches are mixed HP 2610 pwr ,HP 2626 pwr and HP 2626 without pwr in total there is one 3com and 23 HP's

On HP i managed to bring up vlans and they are working corectly but only in its own subnet and across network.Can anybody tell me how to manage inter vlan routing.I have 8 VLANs.

Below is current config of 3com.

192.168.80.254 is default gateway to internet

192.168.80.80 is juniper for VPN connection to remote location

192.168.80.31 is 3com

 Welcome aboard...

I am not a "routing expert" so please bear with me.

What I didn't understand in your post was what routing you wish to do.  If you look at your config, the section on the "route" commands, you will see that you defined the address of the vlan int in the switch as the default route for each of the segments/vlans.  But I don't see where the traffic is supposed to go from there.

For example, if you were trying to all of the vlans to the same segment - say the one with internet access - then in your "route" commands you would want to define that interface.  

ip route-static 0.0.0.0 0.0.0.0 192.168.80.254   <-- your path to internet





 ip route-static 192.168.10.0 255.255.255.0 192.168.80.80  <--- Wouldn't you want this to also be the 80.254, thus the packet is routed from 10.0 to 80.254 interface and then internet beyond?





 ip route-static 192.168.80.0 255.255.255.0 192.168.80.31  <-  route to 3com switch?





 ip route-static 192.168.81.0 255.255.255.0 192.168.80.80  <-- route to VPN box

Do you see what is confusing me?  

Check out "3Com Stackable Switch Family Advanced Configuration Guide" , it has some good chapters on the routing setups including RIP and OSPF.

Sorry if I didn't help any.... I am learning this myself.

OK

first tnx for your aswer

192.168.80.254 is default gateway and i cant access it beacouse it is router from internet provider and a dont have user/pass combination

192.168.10.0/24 is remote location in another city and it is connected through juniper on adress 192.168.80.80

192.168.81.0/24 same thing like 192.168.10.0/24

Would it make any difference if i change route 192.168.80.0/24 from 192.168.80.31 to 192.168.80.254

I would like that all vlans are conected to internet and only some of them to see eachoder.Today I started to create plan for VLANs and it looks like this

vlan80    192.168.80.0/24   manage vlan ,routers ,switches, servers, Avaya Communication server , IT Computers,must see all vlans


vlan90    192.168.90.0/24   Domain users , must see vlan 80 and vlan 110


vlan100 192.168.100.0 /24 toll gates must see vlan80 (192.168.80.254) for internet and toll gates server


vlan110 192.168.110.0 /24 printers,POS hardware must see vlan80 (192.168.80.254) for internet and servers


vlan120 192.168.120.0 /24 Video surveilance must see vlan80 (192.168.80.254) for internet


vlan130 192.168.130.0 /24 IP phones, must see vlan80 (192.168.80.200-201) for Avaya Comm server


vlan140 192.168.140.0 /24 IP phones, must see vlan80 (192.168.80.200-201) for Avaya Comm server


vlan150 192.168.150.0 /24 WIFI must see vlan80 (192.168.80.254) for internet


vlan160 192.168.160.0/24  audio streaming must see vlan80 (192.168.80.254) for internet


vlan170 192.168.170.0/24  reserved must see vlan80 (192.168.80.254) for internet


vlan180 192.168.180.0/24  reserved must see vlan80 (192.168.80.254) for internet


vlan190 192.168.190.0/24  reserved must see vlan80 (192.168.80.254) for internet

i wonder can someone tell me routes that i must deploy in order to make this to work?

tnx in advance
