Hi abMarcin, yes it is possible to utilize all 3 technologies together. 1) VLT for layer 2 redundancy (MLAG) 2) VRRP active/active mode in VLT as first hop router redundancy 3) OSPF in VLT with active peer-routing for L3 upstream redundancy Please have a look at our OS10 VLT guide: [URL] Peer routing in OS10 is no longer considered as an alternative to VRRP as we did not implement certain features but it is helpful to optimize the traffic flow for routed connections (each peer can forward on behalf of it's parter without utilizing the interconnect).

Hello,   Im changing my single router "Cisco ISR" to 2x Dell Switch 4148F-ONI need to utilize: 1. VLT to create VLT Domain and redundancy 2. VRRP active/active for the GateWay 3. OSPF to connect to other routers   Question's are, is it possible to utilize all that featuers together ? Is thing "VLT peer routing" needed to be configured ?  How to configure properly OSPF in such environment?
