Guys,
Can anyone offer an explanation for the following: -
I have allocated a secondary IP address to a FastEthernet interface on my 7204 router running IOS 12.1 using the following command: -
"ip address x.x.x.x x.x.x.x secondary"
[.The interface is running HSRP on the primary address but not on the secondary]
I have an IP helper on the interface to my DHCP server.
I have created an additional superscope on the DHCP server so that I can have 500+ IP addresses on the same wire.
The problem is I cannot see the secondary IP address from the network (cannot ping it from a client machine or even from the router itself). If I do a show run the interface has accepted the address. If I ping the broadcast address for the secondary subnet I get a response from all IP addresses on both the primary and the secondary subnets. If I manually edit a client PC with an IP address from the secondary range but use the primary address gateway as the default then the machine can communicate over the network., but if I allocate the default gateway as the secondary IP address on the interface the client cannot see it??
Any ideas guys?
Regards
Tel
