The next-hop-self neighbor configuration parameter or (most of the) set options of outbound route-map configured on route-reflector clients are ignored for reflected routes. Route reflector does not change or remove any other attributes of the reflected routes (even non-transitive attributes), ensuring that the IBGP routes are not changed within the autonomous system. The value configured with the bgp cluster-id router configuration command (or the router ID of the route reflector if the cluster-id is not configured) is prepended to the Cluster list attribute.If the route does not have the Cluster list attribute, it’s added to the route.If the route does not have the Originator ID attribute (it has not been reflected before), the router ID of the IBGP peer from which the route has been received is copied into the Originator ID attribute.Whenever an IBGP route is reflected (propagated to another IBGP peer), the route reflector appends two optional, non-transitive attributes to the BGP route: Routes received from a route-reflector client and selected as best routes are propagated to all BGP peers (internal and external).Īn IBGP route received from a route-reflector client is sent to all IBGP peers, including the client from which it was received.Routes received from an IGBP peer that is not a route-reflector client and selected as best routes are propagated to all EBGP peers and all IGBP peers configured as route-reflector clients.Locally originated routes and routes received from EBGP neighbors and selected as best routes are propagated to all BGP peers (internal and external).Route Reflector RulesĪ BGP router implementing route reflector functionality propagates BGP routes according to these rules: RFC 4271 defines a new attribute ( cluster list) which can detect route propagation loops within an AS, allowing us to build any IBGP topology we wish as long as we follow a few simple rules. The next revision of the BGP standard ( RFC 4271) already included references to the BGP Route Reflector functionality defined in RFC4456 and augmented in RFC7606.

Thanks for all the contacts particularly for the summit to summits. Total distance just short of 20km and almost 12 hours on the hill.Īpologies to anyone who was looking for an hf contact on the later summits, energy conservation was taking precedence by then. After 6 contacts I packed up for the day and headed back down to the car - very slowly… There were a few other people turned up at this summit but they obviously were doing the route utilizing 2 cars, one at either end, so reducing the mileage walked. Having reached it, I enjoyed the sit down and another 2m fm activation. Splendid as I didn’t have the energy to set up for HF!Īs my car was parked at the east side of the chain, I had to continue in the direction of the third hill anyway and buoyed by the 2m fm success so far, I continued. I got to the summit and tried 2 fm for contacts finding 4 helpful folk waiting for me. After tidying up I set off for the next hill Meall Garbh, pretty tired by the time I’d contoured round An Stuc.

This gave me some hope for the other activations. After 1-hour hf I changed to 2fm and was pleased to receive 6 contacts. Hope I didn’t disrupt your activation, you were readable when I called but then lost the path.

I heard on I/VA-066 but was not able to complete as I disappeared into noise and then he did too. The activation went well with good results from all of the HF bands although there was plenty QSB. Starting from the east, leaving the car at the Lawers Hotel, I was on the hill at 7.30(local), heading up to Lochan nan Cat and then up the head wall behind it turning West to get to Ben Lawers. I planned the trip to Ben Lawers with the intention to tackle all three peaks in the ridge. Ben Lawers GM/CS-001, Meall Garbh GM/CS-004, Meall Greigh GM/CS-026
