If i take off secondary ip address of interface vlan 1, most PCs looses network connection.
All the PC's/Servers are pointing to 172.17.0.250 for their default gateway and have ip address from the same range 172.17.0.0/16
here is what we got.
Two 3750 stacks, serving as core switches for our network. All the workstations (1000) and some servers (20) are on VLAN 1 (I know how this sounds but beleive me it wasn't me who designed it and i am currentlly in a process to segment that).Sswitch1, under interface vlan 1 we two address. Please find config below
If most PCs lose their network connection when you remove the secondary address then it makes me think that the statement that all hosts have addresses in 172.17.0.0 is probably not true. Or if it is not true then there must be some service that they require that is in 22.214.171.124/24. the output of show arp | include 195.169.0 might be helpful in figuring this out.
I also find it very odd to have a primary address in private address space and to have a public registered address as secondary address on the same interface. This sort of suggests that inside and outside are both on the same interface. And maybe that suggests some reason why PCs lose connection if you remove the secondary address.
I also note that having a secondary address on the vlan interface of one switch and not having the address on the vlan interface of the other switch is not a good practice.
Perhaps if you post the output of how ip route we might learn something useful about this problem.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
