1GBit + BGP - Need help choosing router

[secretAlpaca]

Hello, I am about to register an ASN and buy a /24 public range so I can own multiple IP addresses, as my ISP asks for 35$ for one IP.. 

I own a Cisco 1921 ISR that allows me 250mbit and bgp, and I wanted to be able to use a router capable of 1gbit speed and use the bgp function to point to my range to that range i'll buy, 

So my ISP agrees with replacing the ONT/router with a regular ONT non-routed Ethernet port, so I wanted to know what router should I go with?

Thanks in advance

Hello,

not sure what you mean bynon-routed Ethernet port...

Either way, the ISR 4331 or the ASR 1001-X would be a good choice for a replacement...

ISR 4331
