R21.1. Push the MPLS label stack for B. R21.2. Submit the packet to the MPLS engine for transmission. Note: the variable B is defined in Section 4.15 of [RFC8986]. The SRH processing in Section 4.15 of [RFC8986
IGP for SRv6 cannot advertise SRv6 SIDs across ASs. To advertise SRv6 SIDs across ASs, use BGP Egress Peer Engineering (BGP-EPE).BGP-EPE can allocate BGP peer SIDs to inter-AS segments. · If the device has established BGP LS peer relationship with a network controller, it advertises...
An outer IPv6 header and a Segment Routing Header (SRH) are added to the original Layer 3 data packet to form an SRv6 packet.As shown in Figure 4, the value for the Next Header field is 43 in the outer IPv6 header, which indicates that the head...
SD-WAN(Software-Defined Wide Area Network,软件定义广域网) EVPN 是一种通过扩展现有 EVPN 技术来实现 Overlay 业务网络和 Underlay 传输网络分离的VPN 解决方案,用于解决企业分支互联的问题。 SD-WAN EVPN 在 BGP 协议基础上扩展了新的网络层可达信息(Network Layer Reachability Information,NLRI),即:定义了新的...
The SRv6 Network Programming is extended with new types of SRv6 SID endpoint behaviors: uN—A short notation for the NEXT-CSID (Compressed SID) End behavior with a pseudocode of shift-and-lookup, and PSP/USD flavors uA—A short notation for the NEXT-CSID End....
paradigm, making it a powerful tool for implementing intent-driven networks. SRv6 offers a variety of network programming capabilities to better meet the requirements of new network services, and thanks to its compatibility with IPv6, it simplifies the deployment of network services. SRv6 not only...
Else, process as per Section 4.1.1 (Upper-Layer Header) of IETF RFC 8986 SRv6 Network Programming • End.X behavior: If the Upper-layer Header type is 41 (IPv6) or 4 (IPv4), then: 1. Remove the outer IPv6 Header with all its extension headers 2. Forward the exposed IP packet ...
The value must be the same on every platform network wide. This command splits in two the total number of values that can be encoded in 16 bits. A 16-bit field allows values in the range 0x0000 to 0xFFFF. Configuring 16 (default value) for the global-sid-entries value splits t...
