Cisco SG200 and SG300 Inter-Vlan Routing

[nazihhaddad]

Hi,

i need help since i still couldn't figure out how to get Inter-Vlan Routing Work.

i have 2 Cisco SG200 Switches 48 ports (ACCESS L2 SWITCH) and 1 SG300 8  ports (CORE L3 SWITCH) and a Cisco 1941 Router (EDGE Router and  Firewall).

i have created a Vlan 50 on all of my switches then assigned the needed  port to Vlan 50, and configured the uplink ports as Trunk ports then  turned on the IP Routing on my L3 Switch to route between my native Vlan  (Vlan 1) and the newly created  Vlan (Vlan 50) but ping between subnets  still not working knowing that the default gateway on the Vlan 50 PC is the L3 Switch IP address as per the screenshot below.

Please advise since i found lot of difference between cisco native IOS and those switches.

Hello
Can you post your switch configs?

Usually all what is required is:

L3 switch

Int vlan 1
IP address x.x.x. y.y.y.y

Int vlan 50
IP address x.x.x. y.y.y.y

Vlan 50
Exit


Ip routing

Int xxx (connecting to l2 switch)
Switchport trunk encap dot
Switchport mode trunk
No shut


L2 switch

Int vlan 1
IP address x.x.x. y.y.y.y

Ip default-gateway x.x.x.x

Int xxx (connecting to l3 switch)
Switchport trunk encap dot
Switchport mode trunk
No shut

Int xx (access port)
Switchport mode access
Switchport acces vlan 50

SWITCH-L3#

please check the screenshot below.

from the L3 switch i can ping all my internal resources (Servers, Printers, etc ...within the subnet 192.168.10.0/24)

from my VLAN 50 PC i can ping the L3 Switch on its both Vlan's (Vlan1 and Vlan50)

so the route is pretty clear now, but since i can reach the L3 Switch and the L3 Switch can reach all my internal network IP's why can't my VLAN 50 PC Ping the internal network (Servers, Printers, etc...) that is already pingable by the L3 Switch  ?

how did you fixed it? I have the same problem

[nazihhaddad]

Fixed.

it was a routing issue.
