We are changing vendors and are migrating our Cisco switches from Cisco to DELL.
I am now in the process of moving the ISP uplinks from our Cisco core switches to a DELL S5232 VLT-pair. However, I am not sure on how to mimic the Cisco config.
Current (Cisco) situation:
Our Cisco core switches are configured in a VSS pair.
We have a single fiber uplink to 2 ISP and both VSS members are connected to 1 of the uplinks. This situation works well and if 1 of the links go down, the default gateway switches to the working link.
New (DELL) situation:
The big difference in my opinion is that with Cisco we had a single routing table between the VSS peers and this is not the case within a DELL VLT. Moreover routes aren’t synchronized between VLT peers and the VLTi only passes port-channel traffic so these uplink ports are 'orphaned' in some way.
How to make uplink B the backup default gateway for VLT peer A and vice versa?
