N3048 used for iBGP to AWS
Good day, to all.
I have a question regarding a BGP configuration between AWS Direct Connect and on the premises site using a N3048 stack.
I have the BGP session up and running but no routes are being publish. The question is what am i missing in the Dell config.
AWS has a default config for Cisco & Juniper but not for the Dell.
Is there someone who can give me some hints beside RTFM ?
Cisco config example :
! Amazon Web Services
!=======================================IPV4=======================================
! Direct Connect
! Virtual Interface ID: dxvif-fgm4el7u
!
! --------------------------------------------------------------------------------
! Interface Configuration
! interface port-channel 1 (In case of a LAG connection)
interface GigabitEthernet0/1
! channel-group 1 mode passive (In case of a LAG connection)
no ip address
interface GigabitEthernet0/1.2167
! interface port-channel 1.2167 (In case of a LAG connection)
description "Direct Connect to your Amazon VPC or AWS Cloud"
encapsulation dot1Q 2167
ip address 169.254.237.6 255.255.255.252
! Note: Please ensure to remove any individual member port configurations before the EtherChannel is configured.

Please advise would be great.

Thanks.

DellvxCisco,
What you can try is to clear ip bgp to reset the bgp connections and see if it will get the routes, as seen on page 1272 here. You also want to go through the AWS BGP troubleshooting guide, found here. Beyond that I feel like it may be a configuration/design issue and the problem isn't necessarily from our side, so it may be out of our scope.
Let me know how it goes.

Hi Chris,
i did already take the steps you advised. I changed the config a little bit, which resulted is advertising the networks on the dell side in the routing tables.
But vice-versa no routing info received from AWS. I changed the router config to redistribute connected which publishes al the direct connected networks, but if i add a network which is not connected it will not publish, also tried redistibute static .
Any advise ?
