Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 15:23:00 GMT

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).

RE: Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 15:36:00 GMT

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 ?

RE: Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 15:36:00 GMT

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

Ariyakudi_Srini — Tue, 13 Dec 2016 16:28:00 GMT

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

RE: Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 16:28:00 GMT

subnet is active an ospf ready

RE: Adding on X670G2 to an existing OSPF network

OscarK — Tue, 13 Dec 2016 17:02:00 GMT

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

RE: Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 17:02:00 GMT

no change.

Hi Johan, could you please share the output for "show ospf interfaces" command?

Thanks

RE: Adding on X670G2 to an existing OSPF network

Bill_Stritzinge — Tue, 13 Dec 2016 19:35:00 GMT

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.

Bill

RE: Adding on X670G2 to an existing OSPF network

JohanHendrikx — Tue, 13 Dec 2016 19:35:00 GMT

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

RE: Adding on X670G2 to an existing OSPF network

Erik_Auerswald — Tue, 13 Dec 2016 21:43:00 GMT

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.

Erik

RE: Adding on X670G2 to an existing OSPF network

Erik_Auerswald — Tue, 13 Dec 2016 22:35:00 GMT

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

RE: Adding on X670G2 to an existing OSPF network

Parthiban_V — Wed, 14 Dec 2016 11:00:00 GMT

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

RE: Adding on X670G2 to an existing OSPF network
