Holodeck 9 FRR router access

[Frank Bender]

Hello,

is there a way to access the BGP router on the Holodeck-Router for troubleshooting or config?

One point would be to add another AS for NS connectivity of a NSX project.

Thanks

Frank

To add another AS -
1. You can edit the FRRConfiguration CR at /holodeck-runtime/frr/bgpRouterConfiguration.yaml and add the appropriate BGP configuration
2. Apply the CR using "kubectl apply -f /holodeck-runtime/frr/bgpRouterConfiguration.yaml"
3. Restart the daemonset using "kubectl rollout restart daemonset/frr-k8s"

If you want to log into FRR router pod for troubleshooting, use "kubectl exec -it $(kubectl get pods | grep frr-k8s | grep -v webhook | awk '{print $1}') -c frr -- vtysh"

I am now having a bgp peering problem with Holodeck 9.

I deployed a VCF 5.2 environment, but when try to deploy Edge cluster, get the bgp peering fails

There is another article that says edit the gobgpd.conf file on the Cloudbuilder, but the new holorouter in holodeck 9 does not have the gobgpd.conf file.

Any idea on why bgp peer fails?

ALL of the ocnfigs are correct, but the neighbors wont peer.........
I can ping between everything....
I am thinking maybe it is a holorouter issue............any ideas?

Thanks in advance...

Edit the /etc/sysctl.d/kubernetes.conf and add the lines -

net.ipv4.udp_l3mdev_accept=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

save and close the file. 

Run "sysctl --system" and check if that resolves your issues
