MX85 HUB device Routing issues

[Scott3]

HI

I have a three hub network on AUTOVPN. with spokes connected to all three hubs. The hubs act as gateways to existing MPLS network. I connect all three hubs via BGP to the local mpls routers. 

I then set a default "internal route" that sends out to the spokes.

Trouble is one of the hubs  MX85 HA seems to be sending out the learnt routes from the mpls and now all traffic goes via this link as has better matches.

I cannot find out any detail why this is doing it and not the others. the other hub sites are larger and mx250 devices HA.

this is causing all traffic route via the smaller hub rather than the larger ones

the work around i have used is to disconnect this hub from majority of the network.

What MX version are you running ? I think I have seen that issue in the changelogs

Up to date

Current version: MX 16.16

Would need to see more, like a diagram plus access to the dashboard/config to make any suggestions. Sounds like a config problem.

Hi have case  07969187 open for this, should have access to network

"MX85 HA seems to be sending out the learnt routes from the mpls"

Its advertising into autovpn?or mpls routes are advertised back to the mpls router?

All mpls routers are in the same bgp as?

You have not ticket the allow transit box at the bgp config?

[Scott3]

Yes it seems to be advertising the mpls routes out to the spokes but only from the mx85 hub. We do not have allow transit ticket on the BGP config, and all peers to the hubs are in same AS.

That sounds normal. On the spoke you should see the routes from the hub that is first selected on that spoke side. Is the mx85 on top of that list?

[Scott3]

Hi no it was tertiary in some cases.
