Is there somebody using linux bridge runs across the broadcast problem? I have 2 boxes (172.18.17.1/16 & 172.18.17.2/16) running as bridge, sometimes the UDP broadcast can not be sent out from one of them, let's say 172.18.17.2, here is tcpdump logs from it, ~ # tcpdump ether host 00:02:e3:02:98:f5 arp who-has 172.18.255.255 tell 172.18.17.2 802.1d config 8000.00:02:e3:02:98:f5.8001 root 8000.00:02:e3:02:98:f5 pathcost 0 age 0 max 20 hello 2 fdelay 15 The bridge can not realize that 172.18.255.255 is its broadcast!!!
Ath this point, ping 172.18.255.255 on this box, only the box itself replies, here is tcpdump logs from it ~# tcpdump icmp lo > 172.18.17.2 > 172.18.17.2: icmp: echo reply lo < 172.18.17.2 > 172.18.17.2: icmp: echo reply Obviously the packet can not be sent out though its physics interface. The other box can not receive any packets at all. I am using redhat with linux 2.2.19 and bridge patch in my linux box, thanks for any illumination Jianwen _______________________________________________ Bridge mailing list [EMAIL PROTECTED] http://www.math.leidenuniv.nl/mailman/listinfo/bridge
