XG routing not working a vlan interface

Hi all ,

i have 2 vlans in my network on a cisco switch vlan 1 and vlan 2, each assigned on access ports on the switch

i am doing router on a stick model , link between switch and XG is trunk (trunk port on cisco)

on XG , there is a physical lan interface for vlan 1 192.168.1.254 , then a vlan interface on it in vlan 4 192.168.4.254

now ican ping both interfaces from vlan 1
XG can ping vlan 4
but no routing between vlan 1 and 4

rule is allow any any on xg

trace route from vlan 1 to vlan 4 , the xg routes vlan 4 traffic to the wan interface

can any one help ??

Hi Amr Kabary

Please add back route on XG for VLAN 4 network and check the PING/trace route from VLAN 1 machine to VLAN 4 machine.

Backroute you need to add on your switch IP which is connected with XG LAN Port.

This may fix this issue.

thanks for the reply

but this is a router on a stick

in this model you dont create layer 3 interface on the switch
switch port facing xg is a trunk port

Hi Amr Kabary

can you generate the PING and check the packet request on XG ?

You may check the traffic or packet request via below CLI command:

console > tcpdump 'host X.X.X.X.

where X.X.X.X is the destination machine IP

Please share the result here.

Also collect below command output.

console> sy dia utilities netconf route list

Hi,

XG uses layer 3 VLANs and I am surprised that no-one has commented about using VLAN 1 which is not supported on XG.
