Hello Guys, has anybody out there QinQ running between a MX and a Cisco Catalyst? I need some help with such a setup. We got some MX960 and EX3400 boxes to replace some Cisco 6500. On the EX3400 I got tagged and untagged frames forwarded but no STP packets because EX3400 does not support Layer2 Protocol Tunneling yet (box crashes, Juniper says it's on the todo list to implement that feature).
Then I tried to get it running on the MX but have no experience with the really confusing bridging stuff on it. I was able to transport tagged vlans only (but no untagged at the same time), but I need to forward any mix of tagged and untagged together with (M)STP (means I have no clue what the customer uses and contract says we forward everything). Cisco Config for the customer facing ports: interface Gi1/1 switchport switchport access vlan 2001 switchport mode dot1q-tunnel mtu 9216 l2protocol-tunnel cdp l2protocol-tunnel stp l2protocol-tunnel vtp Link to other boxes: interface TenGigabitEthernet9/1 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 2001 switchport mode trunk mtu 9216 Really easy and works great. I tried to adapt the config of the EX3400 to the MX (does not work at all): ------------------------------------------------------------------ Internal Interface (ae1): flexible-vlan-tagging; mtu 9216; encapsulation flexible-ethernet-services; aggregated-ether-options { lacp { active; } } unit 2001 { encapsulation vlan-bridge; vlan-id 2001; } customer facing interface (ge-7/0/0) flexible-vlan-tagging; native-vlan-id 1; mtu 9216; encapsulation extended-vlan-bridge; unit 2001 { vlan-id-list 1-4094; input-vlan-map push; output-vlan-map pop; } show bridge-domains vlan2001 { interface ae1.2001; interface ge-7/0/0.2001; } ------------------------------------------------------------------ Found this with google, but this forwards tagged frames only: ------------------------------------------------------------------ ae1: flexible-vlan-tagging; mtu 9216; encapsulation flexible-ethernet-services; aggregated-ether-options { lacp { active; } } unit 2001 { encapsulation vlan-bridge; vlan-tags outer 2001 inner-range 1-4094; } ge-7/0/0: flexible-vlan-tagging; native-vlan-id 1; <- found no way to set it in the unit 2001, has no effect as far a I see mtu 9216; encapsulation flexible-ethernet-services; unit 2001 { encapsulation vlan-bridge; vlan-id-range 1-4094; } show bridge-domains vlan2001 { vlan-id all; interface ae1.2001; interface ge-7/0/0.2001; } ------------------------------------------------------------------ "set protocols layer2-control mac-rewrite interface ge-7/0/0 protocol stp" also does not work (which seams logically as long as untagged frames do not pass) So what am I doing wrong? Has anybody a working configuration for such a setup? kind regards Rolf _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
