Inter vlan without configuration

[Visconti]

Hi,
We have a problem with our network..
the routing switch serie B5 enterasys is configured as below:
**************************************************************************
#vlan

set vlan create 30

set vlan create 31

set vlan create 40

set vlan create 50

set vlan name 30 "VL-AUTOMAZIONE-PLC-AQ"

set vlan name 31 "VL-AUTOMAZIONE-MGT"

set vlan name 40 "VL-AUTOMAZIONE-PC-AQ"

set vlan name 50 "VL-BADGE-AQ"

clear vlan egress 1 ge.1.1-44

set vlan egress 30 ge.1.45-48 tagged

set vlan egress 30 ge.1.1-22 untagged

set vlan egress 31 ge.1.45-48 tagged

set vlan egress 40 ge.1.45-48 tagged

set vlan egress 40 ge.1.23-44 untagged

set vlan egress 50 ge.1.45-48 tagged

set host vlan 31

#Router Configuration

ip address 192.168.6.254 255.255.255.0 secondary

**********************************************************
But from my pc IP 10.130 vlan 31 I can ping one of pc IP 4.0 vlan 40

Can any one say me the reason ???

Hi Visconti,

Indeed: when routing is enabled, VLANs with IP addresses (routable interfaces, SVIs in 'C' terminology) are routed.

Kind regards,
Tomasz

So will you tell me that to segregate the vlan is not enough to set the switch routing configuration as above?????
I must to set also the "no ip routing" ??????
Would this explain the ping between the various PCs of various VLANs?

Hi,

as per CLI reference guide routing is enabled by default
