Multiple ASN with BGP

I would like to know is it possible to use a VyOS router which can have multiple ASN? We currently have 2 ASN’s issued to us from the respective RIR, will this require 2 separate instances of VyOS or is it possible to have multiple ASN numbers on the same instance? We want to use these 2 ASN to broadcast different set of IP prefixes to our upstream ISP’s.

This is not possible on a Cisco CSR 1000V.

Hi @ideaDC1,

In VyOS, you can use the local-as <XXX> parameter to achieve this, setting up different local speakers for different peers.
Or you can use VRF to split the routing tables logically
