One of the functions can be used part of SRv6 address is End.DT4. End.DT4 profides L3VPN service over SRv6 data plane for the customers who use IPv4 address space. End.DT4 function provides FIB lookup in a specific tenant table (VRF) at the egress PE. This would be equivalent to the per-VRF VPN label in MPLS. When a …
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 …
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. …
SRH is a new type of IPv6 Routing Extension Header and it includes SRv6 SIDs. It may include a Segment List encoded as an IPv6 Address. It is not an exact IPv6 address. You may think like it is just a format and we will call it SRv6 SID. Format is IPv6 address but in …
SRv6 is a new source routing paradigm which means that the source can define the path that the packet will take. There are already some other ways to do this “Source Routing” but SRv6 is candidate to be easiest way. It is possible to run Segment Routing on MPLS Data and IPv6 Data plane. To …
