"High Away Blues Nr 1" or Challenges in Edge High Availability Part 1: VRRP HA
Configuring different High Availability Features one Branch Setup in my lab was using an MPLS CE-Router and VRRP to allow a restricted Fault Tolerance. When the VMware SD-Wan Edge goes down, there is still a working MPLS connectivity via the CE Router, which means the Branch in that case behaves like a NSD (Non-SD-Wan enabled site) and you need to have a forwarding via either a hybrid Partner Gateway or Hybrid HUB site to still be able to reach all necessary destinations. The MPLS-facing CE-Router in my case is a Cisco IOS L3 Router, MPLS connectivity for that customer is using OSPF On the VCO the Edge BR-20 has the corresponding VRRP-setting GE1 is the Link from Edge to the CE-Router using pt-2-pt OSPF In the WAN Settings GE1 is marked as User Defined Wan Overlay of type Private Wired named MPLS-Cust-2 The necessary Enable Wan Overlay Flag is correctly set, telling the Edge to also build Overlay tunnels to Gateways using that connection towards MPLS vi...
