The SoO extended community uniquely identifies the site from which a router has learned a route.

The configuration of an SoO extended community allows routers that support EIGRP MPLS VPN PE-CE Site of Origin feature to identify the site from which each route originated. When this feature is enabled, the EIGRP routing process on the PE or CE router checks each received route for the SoO extended community and filters based on the following ...
Mar 20, 2023 · Site of Origin uniquely identifies the site that has originated the route. Site of Origin is also useful to prevent routing loops and suboptimal routing, especially used to prevent routing loops on dual-homed sites. Site of Origin can be used even when IGP is used between PE-CE routers and can also be used when BGP is used between PE-CE routers.
Use the as-override command in conjunction with the site-of-origin (SoO) feature, identifying the site where a route originated, and preventing routing loops between routers within a VPN.
