If you want to have some real fun, try configuring some class E addresses. Windows of course won't have it, and Cisco also doesn't want anything to do with it, even to the point of rejecting routes within 240.0.0.0/4 when they come in over BGP. (Which an MacOSX box running Zebra will happily provide.)
Class D you mean surely? Note that while GNU Zebra might be configurable to provide such updates, it too rejects such updates if received on unicast IPv4 address family sessions bgp_route.c::bgp_nlri_parse(): /* Check address. */ if (packet->afi == AFI_IP && packet->safi == SAFI_UNICAST) { if (IN_CLASSD (ntohl (p.u.prefix4.s_addr))) { zlog (peer->log, LOG_ERR, "IPv4 unicast NLRI is multicast address %s", inet_ntoa (p.u.prefix4)); bgp_notify_send (peer, BGP_NOTIFY_UPDATE_ERR, BGP_NOTIFY_UPDATE_INVAL_NETWORK); return -1; } } and has done since GNU Zebra 0.91. regards, -- Paul Jakma paul@clubi.ie paul@jakma.org Key ID: 64A2FF6A warning: do not ever send email to spam@dishone.st Fortune: Many receive advice, few profit by it. -- Publilius Syrus
