Logical Interfaces

Hey,

Just a quick question on logical units...

I created some olives and linked them directly via their em2 interface.

Here is the config of R1:

show interfaces em2

vlan-tagging;
unit 100 {
vlan-id 100;
family inet {
address 10.1.1.1/24;
}
}
unit 200 {
vlan-id 200;
family inet {
address 172.16.1.1/24;
}
}

Here is the config of R2:

show interfaces em2

vlan-tagging;
unit 100 {
vlan-id 100;
family inet {
address 10.1.1.2/24;
}
}
unit 200 {
vlan-id 200;
family inet {
address 172.16.1.2/24;
}
}

Here is what I don't understand...

R2 can successfully ping 10.1.1.1 and 172.16.1.1, however, R1 can only ping 10.1.1.2 successfully. When R1 tries 172.16.1.2, it does not get a response.

Am I missing something...

I understand that each router will send tagged frames over to the other since I have configured vlan-tagging and set the vlad-id, however I don't understand why R1 cannot reach 172.16.1.2. These are two olives with their em2 connected via the same VMNET.

Thanks!

You're not missing anything. It should work. Maybe something with the Olive image you are running. I even configured it in my lab just to make sure I wasn't completely losing it (or missing something totally obvious) but it worked fine for me exactly as shown.

Excellent! Thank you for trying it out! Yeah that was confusing me. Good to know the config was right!
