Route reflectors (RRs) propagate only their best path over their sessions by hiding the other paths. This may not be the best path according to client point of view. ORR (Optimal Route Reflection) can solve that kind of problem. Use case for ORR is to avoid reflecting all paths to the client. Because Client may …
When BGP is used to distribute a specific route, it can also be used to distribute an MPLS label which is mapped to that route (Labeled BGP). Label distribution can be in the BGP Update message by using the BGP-4 Multiprotocol SAFI 4. It is used to indicate that the NLRI contains a label. Recall that …
EVPN is a standards-based BGP control plane to advertise MAC addresses, MAC and IP bindings and IP Prefixes. It can be used for both layer 2 services including p2p services and p2mp services and layer 3 services. First standards for EVPN defined to usage over MPLS (including SR-MPLS) data plane but it is also possible …
In today’s network, path control can be achieved with MPLS Traffic Engineering tunnels. These tunnels can be created with protocols like RSVP-TE and CR-LDP. Even for the SR-MPLS and SRv6. When defining paths, both static and dynamic options are available. MPLS TE is deployed today by many operators to optimize network bandwidth usage, to provide …
