Hello All,
I hope you are doing well. I have a question regarding Juniper EX4200.
I have an EX4200 with two port-mode trunk interfaces:
- one facing the customer where I receive many different vlans (10, 20, 30 and 40),
- another one facing a Juniper MX where the vlans are received in different subinterfaces according to the vlans.
Is there a way to do the following:
- Vlans 30 and 40 pass through as normal single tagged frames.
- Vlans 10 and 20 have to be encapsulated in another S-VLAN 100, and pass as VLAN 100 to the MX.
How could I configure this in the switch?
I tried configuring vlan 100 with dot1q-tunneling customer-vlans [ 10 20 ], but it won't work. Please take into account both interfaces are trunk.
I understand set ethernet-switching-options dot1q-tunneling ether-type 0x8100 should be configured, so that in the trunk with Juniper MX both single and dual tagged frames can be sent.
Thank you very much for your help
