Hi,
I would appreciate some advise on the following:
1) If 2 PCs have the same IP address on the network, what would be the impact?
2) If a PC is having the same IP address as the gateway, what would be the impact? How do we track on the network if it happens?
3) What would be the impact when I encountered %HSRP-4-DUPADDR: Duplicate address 192.168.1.1 on Vlan502, sourced by 0000.0c07.ac46? I tried to look into the configurations of the network devices but do not find any duplicate HSRP ip addresses, could it be the external WAN link which is using the same HSRP ip address as the router which causes it?
4) Any impact of having same HSRP groups for 2 different VTP domains?
5) For the above, to avoid unauthorised people to access the network, especially those who plug in a switch to disrupt the network, as well as avoid people from using the same ip address as the gateway, other than or in addition to bpdu guard, is it advisable to implement mac address tie to IP address on the DHCP server? If not, any suggestions?
Thanks
Christina
