Switching

I'm setting up a test environment/lab and am not able to get routing from a host on a vlan to off of the switch on to a separate network.

Vlan33 ( cloud )

Host A ( 192.168.33.10 )

The switch is 192.168.33.1

Vlan5 ( wan )

I have an old router at 192.168.5.1

The switch has an ip 192.168.5.2

HostA can ping 192.168.5.2, but never 192.168.5.1 which leads to the outside world.

I can ping from outside to 192.168.5.2.  And on the 192.168.5.x network I can ping 192.168.5.1.

I have set up other vlans ( 172.16.2 ) and put hosts on them and all the hosts can ping between themselves ( 192.168.33.x  to/from 172.16.2.x ) across vlans with no issues.

I upgraded to 12.3R12.4 tonight but that didn't make a difference.

I have a static route set up:

routing-options {
    static {
        route 0.0.0.0/0 next-hop 192.168.5.1;
    }
}

I'm guessing it's something really simple but any help would be greatly appreciated.

Hello,

On the Router with IP 192.168.5.1, do you have a route to 192.168.33.0/24 pointing tp 192.168.5.2 i.e. EX3300?

I think that should be the problem.

Regards,

Rushi

I think you are absolutely correct!  I woke up this morning thinking that might be it and I'll test it as soon as I can.

Thanks for the pointer!!
