static

IPv6 InBandOAM Analyse node.

Node Identifier:

ip6-hbh-analyse-local, ip6-hbh-analyse-remote

This function receives IP-FIX packets containing IPv6-iOAM records, analyses them and collects/aggregates the statistics.

Parameters

vm	vlib_main_t corresponding to the current thread.
node	vlib_node_runtime_t data for this node.
frame	vlib_frame_t whose contents should be dispatched.

Graph mechanics: buffer, next index usage

Uses:

• vlib_buffer_get_current(p0)
  • Walks on each ioam record present in IP-Fix record, analyse them and store the statistics.

Next Index:

• Dispatches the packet to ip4-lookup if executed under ip6-hbh-analyse-local node context and to ip4-drop if executed under ip6-hbh-analyse-remote node context.
