I have a Cisco Switch 3850X which is totally fibre interfaces. I have created 5 vlan and there is intervlan routing at L3 in the switch. Each vlan has dhcp pool. The switch is further connected to 8 access switches with gigaethernet access ports. At access layer, all the ports are getting dhcp of their respected vlan and can ping to other vlan and their default gateway.
Our internet router has ip address 192.168.8.1 which is normal modem, not Cisco router. To connect to internet, I have created separate vlan 80 and made L3 routing. interface vlan 80 has the ip address 192.168.8.254.
interface Vlan30 ip address 192.168.3.1 255.255.255.0 ! interface Vlan40 ip address 192.168.4.1 255.255.255.0 ! interface Vlan50 ip address 192.168.5.1 255.255.255.0 ! interface Vlan60 ip address 192.168.6.1 255.255.255.0 ! interface Vlan70 ip address 192.168.7.1 255.255.255.0
! interface Vlan80 ip address 192.168.8.254 255.255.255.0
This vlan is assigned to the port in other switch which is having the access vlan 80. And ethernet is connected to the router 192.168.8.1.
I created below ip route
ip route 0.0.0.0 0.0.0.0 192.168.8.1
to point internet traffic to the internet router.
From the main core switch 3850, I am able to ping the router and also innternet dns 126.96.36.199 which means internet is working there. But when my computer is connected to any other vlan IP Address like 192.168.3.0, I am able to ping 192.168.8.254 only. While I can't ping the connected router which is 192.168.8.1. Thus I am not able to ping the internet also or 188.8.131.52 from the PC.
Could anyone suggest the possible reason or solution? Will appreciate your help in this regard.
