I have an issue. We have a Cisco router with 2 Ethernet Interfaces F0/0 and
F0/1. My dhcp server sits on F0/1. On F0/0 I have the following:
interface FastEthernet0/0
ip address xx.xx.xx.177 255.255.255.240
ip address xx.xx.xx.161 255.255.255.240 secondary
ip address cc.cc.cc.1 255.255.254.0 secondary
ip access-group 101 in
ip access-group 102 out
ip helper-address xx.xx.xx.146
When this was set like this I received unknown segment from the DHCP server?
So I then changed it like this:
interface FastEthernet0/0
ip address xx.xx.xx.177 255.255.255.240 secondary
ip address xx.xx.xx.161 255.255.255.240 secondary
ip address cc.cc.cc.1 255.255.254.0
ip access-group 101 in
ip access-group 102 out
ip helper-address xx.xx.xx.146
Now on the router I set cc.cc.cc.1 as the Primary IP on F0/0 and the unknown
segment went away? Why would it matter either way?
