Adding on X670G2 to an existing OSPF network


Userlevel 4
The OSPF network is a X460-24t and two cisco routers. all configured in the same area.

The fimrware of the X460 and the X670 is 16.1.2.14.

But for some reason the X670 is not learning or distribute any route.

How can I troubleshoot this ?

Hello Johan, is neighborship established ? Are area's configured right, is the mtu the same between the neighbors ? Is your license sufficient ? (some edge licenses cannot be DR/BDR).

Oscar, neighborship is established. The license is oke (core). MTU could be the issue.

I wil check this

Hi Johan, If neighborship is established then MTU should not be the problem. What type of route is not getting installed ? Do you have any import policies configured ?

I don't use policies. OSPF config is very basic.

configure ospf routerid
enable ospf
enable ospf export static cost 2 type ase-type-1
configure ospf add vlan area 0.0.0.0

vlanx is not learned form the other neighbor and is not distibuted to the others

From the X670's perspective, check if all the subnets that needs to be advertised are all active and OSPF ready.

subnet is active an ospf ready

To export all IP vlans with ospf use command:
enable ospf export direct cost 2 type ase-type-1

Johan,

Please check the configuration for OSPF "hello timers" and make sure they are the same for both the Extreme and Cisco. If they are different you will not have any communications.

The timers should be oke , because the x460 receive all the routes

Hi Johan,

if OSPF adjacencies are formed, but no routes seen using the link, the problem might be a point-to-point interface configuration on only one of the routers. Since you did not specify point-to-point in the OSPF config you showed us, I would suggest you check if the Cisco is using a point-to-point interface to the Extreme X670G2.

See OSPF neighbor adjacency is "Full" but not adding routes into route table regarding the above suggestion.

Hi Johan,
From your "show ospf interface" output i could see you have configured a broadcast network through the vlan "GIDAT".

Please provide the following details for both x460 and x670 for the further debugging.

show ospf interface
show ospf interface detail
show ospf neighbor
show configuration ospf

Hi Johan,
Your output states that you have 5 routers in the OSPF broadcast domain. 192.168.178.63 is your DR and 10.2.144.254 is your BDR and all other 3 routers are DROTHER.

From my observation i could able to see x670 is in INIT state with the DR (192.168.178.63) and because of that you are not seeing any OSPF routes.

192.168.178.63 10 INIT /DR 00:20:47:29/00:00:00:01 144.2.144.251 GIDAT
None

Do the following in your 670.
1. Ping to the ip interface of DR(RtID: 192.168.178.63) which is configured in the interface which is connecting 670 to the DR ( i believe it is 144.2.144.251). If ping fails, resolve that. It should be the problem.

Thanks,

I can ping the 144.2.144.251.

When I look at the OSPF neighbors I see:

10.216.167.31 10 FULL /BDR 02:03:22:36/00:00:00:05 144.2.144.250 GIDAT None

And the routes are learned. (?) Was it the ping that solve this problem ?

Hi Johan,
Your output states that you have 5 routers in the OSPF broadcast domain. 192.168.178.63 is your DR and 10.2.144.254 is your BDR and all other 3 routers are DROTHER.

From my observation i could able to see x670 is in INIT state with the DR (192.168.178.63) and because of that you are not seeing any OSPF routes.

192.168.178.63 10 INIT /DR 00:20:47:29/00:00:00:01 144.2.144.251 GIDAT
None

Do the following in your 670.
1. Ping to the ip interface of DR(RtID: 192.168.178.63) which is configured in the interface which is connecting 670 to the DR ( i believe it is 144.2.144.251). If ping fails, resolve that. It should be the problem.

Thanks,

I can ping the ipaddress 144.2.144.251

When I look at the OSPF neighbors I see:

192.168.178.63 10 FULL /DR 02:03:22:31/00:00:00:01 144.2.144.251 GIDAT None

The routes are learned now. (?). Was the ping the solution ?

No Johan. Just to check the reachability i asked you to try a ping. If Ping fails, for sure OSPF will not establish its neigborship.

If there is no issue in reachability and OSPF still stays in INIT state we could have went to the next step of debugging.

After the ping the INIT state is changed in the Full state. So it seems that the problem is spontaneously disappeared.

What would be the next step of debugging?
