I Cant make ospf between two Extreme Swichtes through a L2 link with a LAG configuration between then?

Edison — Tue, 09 Aug 2016 05:53:00 GMT

Hi everybody, I'm having a problem with two switches that are connected via a L2 Service Provider, and there is a LAG between one of the switches and the SP Switch. This LAG is up, but when I actívate the OSPF I cant make the switches run the OSPF. Down I show the relevant configuration. The vlan betweem them is 3794

Switch1:
enable ospf
configure ospf add vlan B-Lim-Ar area 0.0.0.0
create vman "B-Lim-Ar"
configure vman B-Lim-Ar tag 3794
configure vman B-Lim-Ar add ports 12 tagged
configure vlan B-Lim-Ar ipaddress 60.60.60.1 255.255.255.248
enable ipforwarding vlan B-Lim-Ar
configure ports 12 display-string TO_B
configure ports 12 auto on speed 1000 duplex full
configure ports 12 ethertype secondary

IP addr Ospf State DR IP addr BDR IP addr
60.60.60.1 /29 E DR 60.60.60.1 0.0.0.0

Switch2 with LAG:
enable ospf
configure ospf add vlan AqpLima area 0.0.0.0
create vman "AqpLima"
configure vman AqpLima tag 3794
configure vman AqpLima add ports 44 tagged
configure vlan AqpLima ipaddress 60.60.60.2 255.255.255.248
enable ipforwarding vlan AqpLima
configure ospf add vlan AqpLima area 0.0.0.0
configure ports 44 display-string TO_Bit

I have tried it with LAG algorithm address-based L2 but its the same problem. The SP switch is Huawei. Thanks in advance for your suggestions.

Hello Edison,

I do not think you can use routing (or layer 3 forwarding) on a VMAN, you would need to use a VLAN. I wonder how you can have both a VMAN and a VLAN with the same name.

I have made the configuration with:
configure vman B-Lim-Ar ipaddress 60.60.60.1 255.255.255.248,
but when I watch it in show configuration it shows:
configure vlan B-Lim-Ar ipaddress 60.60.60.1 255.255.255.248

Do you have IP connectivity between the two interfaces?
ping 60.60.60.2 from 60.60.60.1ping 60.60.60.1 from 60.60.60.2Erik

Yes I do have ping between them.

The most likely cause is the licensing on the switches. Do a "show license" and make sure at least one of them has a core license installed, if you don't that one can never be the DR. Without a DR you need to configure the links as point-to-point.

I have just check it and both have core license, please if you know the commands to configure point-to-point OSPF I would aprecciate it.

Hello Edison,

that would be:
configure ospf add vlan VLAN_NAME area AREA_ID link-type point-to-pointErik

Ok Thanks

Thinking about this, I do not think OSPF will work on a VMAN even if you can ping it. Can you configure it on a VLAN and try again?
