Company E wants to deploy Cisco SD-WAN with controllers in AWS. The company's existing WAN is on private MPLS without Internet access to controllers in AWS. An Internet circuit is added to a site in addition to the existing MPLS circuit. Which interface template establishes BFD neighbors over both transports?

Question

Accepted Answer

A. Image showing Tunnel configuration with 'Tunnel Interface' On, 'Color' mpls, 'Restrict' On, 'Maximum Control Connections' default (not 0), 'vBond as Stun Server' On, 'Exclude Controller Group List' selected, 'vManage Connection Preference' 5, 'Port Hop' On, 'Low-Bandwidth Link' On. This configuration allows the MPLS tunnel to establish control connections to vSmart and vManage (as Maximum Control Connections is not 0), which is essential for the TLOC to participate in the overlay and establish BFD data plane tunnels. The 'Restrict' setting as 'On' means this MPLS tunnel will form BFD only with other MPLS tunnels.

Answer

B. Image showing Tunnel configuration with 'Tunnel Interface' On, 'Color' mpls, 'Restrict' Off, 'Maximum Control Connections' 0, 'vBond as Stun Server' On, 'Exclude Controller Group List' selected, 'vManage Connection Preference' 5, 'Port Hop' On, 'Low-Bandwidth Link' On. Setting 'Maximum Control Connections' to 0 prevents this TLOC from establishing any control plane connections, which makes it unable to fully participate in the SD-WAN overlay and establish BFD data plane tunnels.
