Description
Advertise routes assigned with specific fabric colors. BGP advertises the routes based on the color configuration without relying on a routing policy. When a neighbor is colored, only routes with the same color or uncolored routes are allowed to be advertised via this neighbor. If there is a color mismatch on the receiver side, the receiver marks the route as hidden. You can advertise uncolored routes over any colored or uncolored fabrics. To advertise specific colored routes over a colored fabric do not have any uncolored routes except for those carrying light control traffic only.
BGP deterministic path forwarding (DPF) divides a physical fabric into multiple logical fabrics, mapping different flows to different logical fabrics.
Options
| route destination | Specify a route that you want to advertise. | |
| backup-color backup-color | (Optional) Configure route advertisement with a backup color. The route is advertised over the primary and backup colored fabrics with the corresponding BGP color community. | When both color and backup-color are configured for a fabric-advertise route, an AIGP metric of 0 is added to the route. This metric signals the receiver to prefer the route when advertised over primary color neighbors. |
| color color | (Optional) Specify a color to advertise the route over EBGP neighbors of the same color. The color community is also added for the route advertised over the colored fabric. |
