Tracing Rules

 Rules when tracing through vxlan tunnels.

  1. Trace to tunnel endpoint IP until we reach the tunnel endpoint
  2. Do not specify a vrf while tracing through vxlan tunnel
  3. After reaching vxlan tunnel endpoint, start tracing to the main source/destination IP again, this time specifying a vrf

MPLS tracing

When tracing through MPLS think of the MPLS destination IP as a vxlan tunnel endpoint. When you see "BGP multipath," that indicates MPLS. Do a show IP route to that IP without specifying a vrf to get your next hop.

Once on the next hop (e.g., ) do:

traceroute mpls ipv4 <MPLS destination IP>/32

show route <first IP in the traceroute>
