Configuration Example for MLAG

This configuration example shows how to configure MLAG (Multi-switch Link Aggregation Group) with VXLAN. In the following example:
  • The MLAG switches are operating as independent OSPF (Open Shortest Path First) 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.
