WebMar 12, 2008 · In case a RR inserts a route into the BGP table (network command or redistribution) it does not behave as a RR, but as a normal iBGP speaker, thus does not attach cluster ID to the newly created route. This behaviour was observed in your test lab: the cluster ID was not seen for 2.2.2.0/24 inserted into BGP by the RR. The cluster ID …

By default cluster ID is set to the BGP router id value, but can be set to an arbitrary 32-bit value. Multiple cluster IDs (MCID) feature allows to assign per-neighbor cluster IDs. Thus, there are 3 types of route reflection scenarios.

WebThis step is skipped if the BGP is configured to compare the router-ID or the paths have the same router-ID. A path with the lowest router ID is preferred. The router-ID can be manually set or it can be set automatically using the highest IP address configured (first the loopback interfaces are considered and then the physical interfaces).
