Forwarding Table

  • Emmanuel pointed out that combining metrics of different routing protocols should not be considered
  • Oleg asked about a concept to store different address types
  • Martin replied that full IPv6 addresses (128 bits) should be supported, but maybe in a separate data structure
  • Oleg reported that Fabian Nack at FUB might start work on this topic soon with a focus on multi-transceiver support
