Changing IP address

kjefferson1

We are working on changing IP Address from 192.168.x.x to a 10.40.x.x and we have give all of the new subnet to AT&T but like to know what changes would we have to make on are Switches and ASA to make this go easy with out bring down the network

Hi there,

It depends on your Layer3 topology. Any L3 switches or routers will support secondary IP addresses on their interfaces. This will allow you to configure VLANs which can support more than one subnet at once. So for any VLAN/ L3 interface you can configure both a 192.168.0.0/16 and 10.40.0.0/16 address and migrate the hosts between the associated subnet without too much disruption.

 

The ASA does not support secondary IP addresses, so you will need to have an out of band method of connecting to the ASA (or console access) when you change its routed interface IP addresses.

 

cheers,

Seb.

Thank you we have two Nexus 3500 for are core switch and we are using a AT&T manage firewall and wealso have a Cisco ASA but only using it for VPN. so what we are looking to do is see what changes we need to make on are side as far as are switches. Not sure of the step that we need to do 

 

Hi there,

I suggest you work one routed interface (physical/ SVI) at a time.

 

For example if you had VLAN10 which used the subnet 192.168.10.0/24 and you wanted to migrate its hosts to 10.40.10.0./24, then configure the SVI like so:

!
interface vlan 10
  ip address 192.168.10.254 255.255.255.0
  ip address 10.40.10.254 255.255.255.0 secondary
!

Then start moving hosts on that VLAN to the new subnet. Either via static interface configuration on the devices themselves or through DHCP (ensuring that the new subnet scopes exist on the DHCP server).

Once the hosts are migrated, make a final change to the SVI:

!
interface vlan 10
  no ip address 192.168.10.254 255.255.255.0
  ip address 10.40.10.254 255.255.255.0
!

Make sure that any other routers in your network are aware of the new 10.40.0.0/16 subnet. Either update static routes or preferable advertise the new subnet via IGP.

 

Finally look at migrating the link to the firewall. As I previously said, the ASA does not support secondary IP addresses on interfaces so you would incur some loss of outbound connectivty whilst the ASA IP address was changed.

 

Are you running a IGP between the ASA and Nexus? If so there are some options we could explore to eliminate the disruption.

 

cheers,

Seb.

Thanks for the help

Both blocks of config are the same, and you aren't moving from a 192.168.0.0/16 subnet.
