Field Documentation

fib_node_index_t gre_tunnel_t::fib_entry_index

The FIB entry sourced by the tunnel for its destination prefix.

Definition at line 106 of file gre.h.

u32 gre_tunnel_t::hw_if_index

Definition at line 99 of file gre.h.

adj_index_t gre_tunnel_t::l2_adj_index

an L2 tunnel always rquires an L2 midchain.

u32 gre_tunnel_t::l2_tx_arc

on a L2 tunnel this is the VLIB arc from the L2-tx to the l2-midchain

Definition at line 119 of file gre.h.

fib_node_t gre_tunnel_t::node

Linkage into the FIB object graph.

Definition at line 85 of file gre.h.

u32 gre_tunnel_t::outer_fib_index

The FIB in which the src.dst address are present.

Definition at line 98 of file gre.h.

u32 gre_tunnel_t::sibling_index

The tunnel is a child of the FIB entry for its desintion.

This is so it receives updates when the forwarding information for that entry changes. The tunnels sibling index on the FIB entry's dependency list.

Definition at line 100 of file gre.h.

ip4_address_t gre_tunnel_t::tunnel_dst

The tunnel's destination/remote address.

Definition at line 94 of file gre.h.

ip4_address_t gre_tunnel_t::tunnel_src

The tunnel's source/local address.

Definition at line 90 of file gre.h.
