Peer Routing Configuration Example
This section provides a detailed explanation of how to configure peer routing in a VLT domain.
In the following example, devices are configured as follows:
Access switch A1 is connected to two VLT peers (Dell-1 and Dell-2).
The two VLT peers are connected to an upstream switch R1.
OSPF is configured in Dell-1, Dell-2, and R1 switches.
Dell-1 is configured as the root bridge.
Dell-1 is configured as the VLT primary.
As the Router ID of Dell-1 is the highest in the topology (highest loopback address of 172.17.1.1), Dell-1 is the OSPF
Designated Router.
As the Router ID of Dell-2 is the second highest in the topology (172.16.1.1), Dell-2 is the OSPF Backup Designated Router.
