LSP ping and trace for segment routing tunnels

To check connectivity and trace the path to any midpoint or endpoint of an SR-ISIS shortest path tunnel, SR Linux supports the following OAM commands:

tools oam lsp-ping sr-isis prefix-sid <prefix>
tools oam lsp-trace sr-isis prefix-sid <prefix>

Supported parameters include destination-ip, source-ip, timeout, ecmp-next-hop-select, igp-instance, and traffic-class. However, the only mandatory parameter is the prefix-sid.

Results from the lsp-ping and lsp-trace operations are displayed using info from state commands.

In the case of ECMP, even when the destination IP is configured, the SR Linux node may not exercise all NHLFEs.

For more information, see the SR Linux OAM and Diagnostics Guide.
