    Figure 2: GRE Tunnel routed over LSP TunnelNetwork topology map showing nodes such as ATL, BOS, and NYC with connections labeled by interface names, IPs, and types. Color-coded links indicate utilization levels with red for high congestion. Detailed path info from ATL to BOS is provided at the bottom.

  4. Note that a tunnel itself can route over a tunnel (in this case, an LSP tunnel). The portion that travels over another tunnel is colored in purple.
