Hi there, I m having problem configure the following lab, could someone help me out, please? my problem is I cannot ping PC1, PC2, PC3 each other. Is my subnetting wrong or something else? Thanks so much for ur time.
Here is the configuration.
172.16.0.0/16 network to be subnetted for :
HQ LAN 500 hosts
BRANCH1 200 hosts
BRANCH2 100 hosts
192.168.1.16/28 address space must be subnetted to obtain the addresses for the links between the three routers.
Here are all the subnettings.
HQ LAN 172.16.0.0/30
BRANCH1 LAN 172.16.2.0/24
BRANCH2 LAN 172.16.3.0/25

network 172.16.0.0 <----depending on the IOS version you're running, make sure that auto-summarization is off ( no auto-summ) and advertise only the specific subnet on the router. Each router now thinks that it is the has direct connectivity with the PC you're trying to ping. Do this on all three routers.

Of course this is only a guess after a quick glance at your configs.
