Configuration Example for MLAG
This configuration example shows how to configure MLAG with VXLAN. In the following example:
- The MLAG switches are operating as independent OSPF routers. They must use different router IDs.
- The same local endpoint address is configured on both switches.
- The ISC link also functions as a routed link with a high metric. The link is also used when one switch loses all underlay connectivity.
