Re: DVMRP routing loop

[Bill Fenner <]

Speaking of duplicates, I'm seeing duplicate packets yet again between
upper-gw and lower-gw.  This pair of routers seem to periodically get
into a state where they create lots and lots of duplicates (in this
particular case it's only 14 copies of each packet).

  Source        Response Dest    Overall     Packet Statistics For Traffic From
130.240.34.6    224.0.1.32       Packet      130.240.34.6 To 224.2.0.1
     |       __/  rtt  416 ms     Rate       Lost/Sent = Pct  Rate
     v      /     hop -204 s     -------     ---------------------
...
193.10.80.33    upper-gw.sunet.se 
     |     ^      ttl   19        57 pps      -26/2    = --%   0 pps
     v     |      hop  156 ms
193.10.80.34   
192.36.148.197  lower-gw.sunet.se 

Can someone please look into this?

Thanks,
