VRRP or static routes with equal weight?

Hello,

I have a bunch of switches, 2 of them act as the core/distribution layer and all remaining are edge switches.

All my inter VLAN routing for all internal services is done at the core/distribution switches, leaving my 2 routers to route traffic to and from the WAN.

I am trying to decide whether i should do VRRP between the routers and then configuring the VRRP IP as the default-gateway in my core switches OR if i should just configure static routes with equal weight to the routers from the core switches...

Thanks

Id give it a shot. Those Vyatta boxes should be able to handle the extra load, and it won't place any more of a burden on your 2 switches.

Well, i was trying to figure out which one option would be best...

VRRP on the vyatta and set the VRRP as the default gateway on the core switches, Or set each core switch with static routes with equal weight to each vyatta router...

VRRP - period.

Equal weight statics will load balance traffic, but not provide and redundancy. If one of the gateways fail, you'll still try to send ~50% of the traffic at it (*ish* but I won't get into the weeds), and any traffic headed to that gateway (see also: route-cache, flow cache, etc.) will suddenly stop. There are ways to go with statics, but it takes more than just the route.

[* disclaimer: I used to make / sell load balancers that did just that using statics ]
