we have 4 byte ebgp ASN ( 123456)
we have four own ip pools as per given bellow (e.g)
at present all above pools are working at our HQ with same ASN (123456)
now we are start internet service at different location with same ASN (123456)
i need to use 128 ips ( 220.127.116.11/25) for 2nd location.
Should i remove of this network pool from HQ Router and add to 2nd location router with Same ASN (123456) ??
i am confuse about that.
>>> can i use same ASN in multiple location ???
>>> can i use my own ip pools after remove from my HQ router which is use at present in BGP network and then add in my 2nd location ( 18.104.22.168/25) ??
Please help me

Hope to help
no, you don't need to remove the /22 prefix in order to be able to advertise /25 component.
Because most specific route is used first.
All you need as noted by Dinesh is to make agreements with the two providers in order to have them to accept the /25 prefix.
The /25 prefix will live only within ISP1 AS and ISP2 AS not in the big internet but this should be enough to achieve the desired effect.
Hope to help
If you have internet service with same provider for both HQ and other location then you can advertise just /25 from you new location without any change in HQ. It's up to provider to advertise you segment.
