Features

LISPmob supports the following features, as specified by draft-ietf-lisp:

Data plane (lisp.ko and lisp_int.ko)

• lmn0 virtual interface
• IPv4-in-IPv4 encapsulation
• IPv6-in-IPv4 encapsulation
• Receiving Loc-Status-Bits (LSB) information
• Many control plane functions below also need support from the data plane

Control plane (lispd)

• Map-Register with a statically configured shared key to a single Map-Server
• Map-Notify messages are verified for validy and the result is logged
• Mapping lookups using a single, statically configured Map-Resolver
• Sending Solicit-Map-Request (SMR) messages to all RLOCs in the map-cache and to a statically configured list of P-ITRs
  • P-ITR list needs to be manually maintained in the configuration file, check the LISP beta network map for more info
• Sending SMR-invoked Map-Requests using a single, statically configured Map-Resolver
• Replying to (Encapsulated) Map-Request messages
• RLOC probing
  • Probe interval is a compiled-in constant, currently 30 seconds
  • Two probes are sent at an interval of one second, the corresponding RLOC is put in "Down" state after a timeout without a reply
  • Probes are sent for "Down" RLOCs as well, which are put back "Up" once a reply is received
• NAT traversal
  • Code on the 'natt' branch.
  • Compatible Map-Server and Re-encapsulating Tunnel Router (RTR) are needed.
  • No manual configuration required.

Tools

• lispconf can be used to query the kernel module for information such as map-cache or database contents
• TCP and UDP echo client/server for basic functionality testing

Some features are not yet fully compliant with the specification. This page will be expanded to note the missing bits.
