Typedef Documentation

lisp_gpe_adjacency_format_flags_t

typedef enum lisp_gpe_adjacency_format_flags_t_ lisp_gpe_adjacency_format_flags_t

Flags for displaying the adjacency.

lisp_gpe_adjacency_t

typedef struct lisp_gpe_adjacency_t_ lisp_gpe_adjacency_t

A LISP GPE Adjacency.

A adjacency represents peer on an L3 sub-interface to which to send traffic. adjacencies are thus present in the EID space. The peer is identified by the key:{remote-rloc, sub-interface}, which is equivalent to the usal adjacency key {next-hop, interface}. So curiously the rloc address from the underlay is used as a next hop address in the overlay This is OK because: 1 - the RLOC is unique in the underlay AND there is only one underlay VRF per overlay 2 - the RLOC may overlap with an address in the overlay, but we do not create an adj-fib (i.e. a route in the overlay FIB for the rloc)
