VLT OSFP VRRP

Hello,

 

Im changing my single router "Cisco ISR" to 2x Dell Switch 4148F-ON

I 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?

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:

https://infohub.delltechnologies.com/static/media/0b6521c4-1d7a-41c5-953d-daf48e8a08e0.pdf

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,

I know this has been rightfully closed many moons ago but I haven't found a configuration guide specific about OSPF and VLT working together in OS10 in the provided link.

Has it moved or is there a better link with more documentation/guides?

Thank you,

Dany
