Re: ONOS BGP-LS Error

[Alessio Giorgetti]

Dear Philippe,

ONOS is mainly an open laboratory on SDN networks. Many popular features are very stable and reliably implemented. Other features have been partially implemented and can include many problems.

As far as I know, BGP-LS is not one of the most popular features. If something doesn't work as expected, the only way is to open the code, understand the problem, and try to fix it.

The community will certainly appreciate your contribution.

Good luck,

alessio

Oggetto: ONOS BGP-LS Error

Airbus Amber

 

Hello ,

 

I hope you're doing well.

I am having some issues in implementing BGP-LS with ONOS. I tried with ONOS 1.7, ONOS 2.4 and ONOS 2.7 but I come across the same problem each time.

First it should be noted that my architecture in which I am trying to use BGP-LS with ONOS is a service provider environment with MPLS and IS-IS as IGP. my architecture is quite heterogeneous (more than 15 routers) with cisco routers (IOS XE and IOS XR) and Juniper routers (Junos).

I tried to establish a peering between ONOS and a Cisco IOS XR router in order to trace the topology of my network and I come across the same error each time in the ONOS logs, namely "Packet length should not exceed 4096 " . this is also the same error I get when I also test peering with a Cisco IOS XE router and a Juniper Junos router.

I would like to know if you know how to solve this problem there and how I must install ONOS to no longer encounter this error as well as the configuration to apply.

I thank you in advance for your help.

Attached are some screenshots of the error I am facing.

 

Best Regards

 

Philippe SEKA
