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

[Edison]

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

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.

Hi Prashanth

Hi,

I have created the vman and configured ipaddress, ipforwarding and OSPF to the same string/name but using vlan word instead of vman.

SW-A ----- 23 ---- OSPF ---- 11 ------- SW-B

SW-A:

create vman "B-Lim-Ar"configure vman B-Lim-Ar tag 3794
configure vman B-Lim-Ar add ports 23 tagged
configure vlan B-Lim-Ar ipaddress 60.60.60.1 255.255.255.248
enable ipforwarding vlan B-Lim-Ar
configure ospf add vlan B-Lim-Ar area 0.0.0.0 link-type point-to-point
enable ospf

SW-B:

create vman "B-Lim-Ar"configure vman B-Lim-Ar tag 3794
configure vman B-Lim-Ar add ports 11 tagged
configure vlan B-Lim-Ar ipaddress 60.60.60.2 255.255.255.248
enable ipforwarding vlan B-Lim-Ar
configure ospf add vlan B-Lim-Ar area 0.0.0.0 link-type point-to-point
enable ospf

Neighbor ID Pri State Up/Dead Time Address Interface
========================================================================

2.2.2.2 1 FULL /DROTHER 00:00:03:36/00:00:00:06 60.60.60.2 B-Lim-Ar

OSPF Neighbor established and I could see all routes learned by its neighbor.

That's interesting... 🙂

Hi Erik, just updated the article.

Thanks for pointing this. 

Hello Henrique,

for your consideration: for a documentation article it would be more appropriate to use IP addresses from the ranges reserved for documentation (https://tools.ietf.org/html/rfc5737), e.g. 192.0.2.1 and 192.0.2.2.

Thanks,
Erik
