Hi, i run a small wireless isp, and currently i use 1 Mikrotik router and im wanting to run another in tandem for redundancy, is this possible without causing problems and IP conflicts?

Much appreciated
Simon

create vrrp for each server (as your question subject is)
plz explane more about what you want

...or use an external Radius that supports Framed-Ip-Pool (like Freeradius) and add as many pppoe-servers as you need.
