VRRP Preempt Delay

RouterOS General

Mikrotik,

anyway to include a feature in the code for preempt the delay of VRRP; currently, if there are 2 routers configured for VRRP and one router fails, the other will resume Master. One issue that I have noticed when using BGP and VRRP on the same box, there is and can be a few more seconds of covergence time for BGP, so when router 1 preempts for Master, traffic is blackholed until router1 receives the BGP full-time.

Hi Gearhead,

What we found to be most stable in production is to rather establish a BGP session on each router with their next-hop defined as the VRRP IP.

That way the failure has no impact on traffic flow. It also allows for a more consistent ‘ready state’. In other words there’s no question in regards possible BGP flap dampening or any other possible transient BGP issues.

Just a ‘food for thought comment’
