soofiahtesham · ‎08-10-2010

Hello All,

As the heading says

I am looking to change the IP on one of my loopbacks

Current Settings :

interface Loopback4

ip address 206.186.192.209 255.255.255.255

Desired Setting :

I need to change the Ip to 206.186.197.134/32 on the above mentioned loopback.

Can any of you please suggest the simplicit way to do that. Also will this cause any disaruption in service.

Thanks in advance,

Soofi!

router(config)# int loopback 4

routerconfig-if)# ip address 206.186.197.134 255.255.255.255

as for disruption depends on what it is used for. Also bear in mind if you are advertising this loopback into a routing protocol you may need to add the new IP under your router config.

Hi

Simply writing a ip configuration commads for any interface of router.

Router>en

Router#conf t

Router(Config)#int loopback4

Router(Config-if)#ip address

Router(Config-if)#no shut

this will configure any loopback ip at any point of time.
