two Cisco2811will loose connection to PC(ping- t) behind Cisco2950 , will loose connection
Posted on 2007-04-06
two Cisco2811 by FE0/0 (10.10.200.101 and 10.10.200.102) connected to Cisco2950(10.10.21.100), as well PC (10.10.10.1/15 gaetway10.10.21.100).
Behind both 2811 16port switch(VLan1 witn 10.15.200.1/28 and 10.15.200.16/28) equipment with IP -10.15.200.2 connected to one 2811 16port switch with 10.15.200.1 and 10.15.200.17 connected to one 2811 16port switch with 10.15.200.16.
When I do ping both equipment from PC, it will loose connection periodicly, and can be restored either by "repair" in WinXP or unpluged/reset one of the links to equipments(10.15.200.2 and 10.15.200.17), and bothh will be "online".
When connection is lost to 10.15.200.2/17 and I do "tracert" , instead of showing 2 hops of corrects route, it will show only one hop of the other router, where is no equipment attached.
Looks like 10.15.200.2/17 routs is not hold by 2811, or some other config/IP assigmnet problem.
Please help what is holding me here? Should I separate FE0/0 by subnetting them? Right now ther are Cisco2881#1 FE0/010.10.200.101,Cisco2881#2 FE0/010.10.200.102,Cisco2881#3 FE0/010.10.200.103,Cisco2881#4 FE0/010.10.200.104 all suppose to be connected to Cisco2950 10.10.21.100.
RIP,Ospf,IEGRP disabled and this is "stand-alone" wiring.
