Everyone,
I'm in the process of changing my internal IP addresses and ran into a
problem on the first site I went to swap. Clients obtain their ip from a
dhcp server at my location, so I added a secondary ip address to the remote
router as shown below:
interface Ethernet0
ip address 172.16.x.x

WHen the DHCP packet is forwarded, the DHCP relay agent will insert the
primary IP address of the interface the packet was received on into the
DHCP packet's giaddr field.
When adding secondaries to an interface where you're doing DHCP, make
sure:
- routing to the primaries and secondaries is
3 matches
