Hi Bryan,
I do not have any other connections between the routers and I am using
12.4(23), but I have tested this on 12.3 as well and its the same
problem.
I am pasting my dynamips connections below and would appreciate if
anyone in the group could try this and let me know if it is the same
problem with him/her as well. The router configurations have already
been given in one of my mails before.
autostart = False
[localhost:7200]
workingdir = C:\Program Files\Dynamips\sample_labs\working\test
[[3640]]
image = C:\Program Files\Dynamips\images\c3640-ik9o3s-mz.124-23.bin
ram = 96
disk0 = 0
disk1 = 0
idlepc = 0x605f00fc
ghostios = True
sparsemem = True
[[Router R1]]
model = 3640
console = 2001
autostart = False
F0/0 = R3 F0/0
[[Router R3]]
model = 3640
console = 2003
autostart = False
slot1 = NM-1FE-TX
F1/0 = R5 F1/0
[[Router R5]]
model = 3640
console = 2005
autostart = False
slot1 = NM-1FE-TX
F0/0 = SW1 F0/0
[[Router SW1]]
model = 3640
console = 2007
autostart = False
Thanks in anticipation
Ravi
