Solved: network mgiration testing - cant ping between networks

tsrader · ‎02-07-2007

lab test config

wan_rtr (new)-10.10.150.1

wan_rtr )old)-172.16.0.1

problem:

wan_rtr(new) cant ping any vlans on 3750_new (it can ping 10.10.151.2)

wan_rtr(new) cant ping 3750_old, 2950(old)

wan_rtr(old) CAN ping 3750(old), 2959(old)

wan_rtr(old) can't ping any vlans on 3750_new

summary: can't ping between the two networks.

I'm sure this is simple routing issue but i'm missing it somewhere. thanks for any help.
