SRv6 End.X Function

In Segment Routing Architecture IGP Prefix Segment Identifer (Prefix-SID) is a Global Segment, advertised by ISIS or OSPF and associated with a prefix, commonly with a loopback ip address. It is also called Node SID. Segment Routing Adj-SIDs usually represent a link (peering) and have a local significance. In SRv6 SID we have Locator and Function.  Locator: Routed to the node …

In today‚Äôs 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 …


SRv6 End Function

Segment Routing architecture can be applied to MPLS data plane and IPv6 data plane (SRv6). IN MPLS Data plane IGP Prefix SID and IGP Adj SIDs (Adj-SID) are used for traffic engineering. (Segment Routing IGP Segments). An SR Policy may use both Prefix SID and Adj-SIDs which are encoded as mpls label or label stack. …
