Hello Comunity,
Share a problem with vrrp redundancy in sdwan environment.
I have a site with 2 edges, one with a link to mpls, and no internet conectivity, and the other with a link to the internet and connectivity to the controllers. Both edges extend connectivity with tlocextension.
For LAN I have vrrp.
Attached drawing for better understanding.
For routing to be symmetric, OMP preference is given to the edge with the vrrp master, in this case the one with internet connectivity.
Everything works fine until an internet outage occurs and control-plane is lost. However the data-plane is up and runnig, the edge with mpls connectivity became master, but since the edges does not reach the controller they can't update the preferences in the OMP routes to match the new vrrp master. And so i lost the LAN side.
I also try to work with the tracks in vrrp, but dont have any changes to the output.
Is there any form of dynamic engineering to overcome this?
Thanks for sharing knowledge.
