A gateway is a device that ensures communication between VXLANs identified by different VNIs and between VXLANs and non-VXLANs. With the distributed gateway routing Layer 3 gateways are configured on leaf devices. With the distributed gateway deployment a leaf node only needs to learn the ARP entries of servers attached to it. VXLAN routing of …
TI-LFA also takes into account is SRLG exist in the network. Shared Risk Link Group (SRLG) is a set of links at the same risk of faults. If a link in an SRLG fails, other links also fail. In this case, if the other link in the SRLG functions as FRR backup to protect the failed …
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 …
A gateway is a device that ensures communication between VXLANs identified by different VNIs and between VXLANs and non-VXLANs. With the centralized gateway routing Layer 3 gateways are configured on one device, usually on Spine layer. It is the easiest way of deploying gateways but it has some disadvantages; There will be a lot of …
In the MPLS Data plane, we have a lot of experience over P2P L2VPN services. SRv6 can provide same functionality with MPLS Data plane and MPLS VPN label. Instead of MPLS Tunnel label and VPN label we can use Segment Routing Header (SRH). SRH is a new type of IPv6 Routing Extension Header. Any kind of function …
VxLAN is becoming de facto standard for the Data Center networking envitoments. In current and future implementations, VxLAN provides an overlay over a Data Center Spine-Leaf networks. It is decoupled from the Underlay which is static and robust. In the early implementations of Data Center Networks, there was no such a thing that applications are …
IGP provides mechanisms through which Segment Routing interoperate with LDP. The control plane of segment routing can co-exists with LDP. If you plan to migrate from LDP to Segment Routing, or if you have some routers which does not support Segment Routing but you still want to use Segment Routing, Interoperability of SR and LDP will …
TI-LFA can add one or more segment when switching traffic to backup and loop free alternate path. According to below topology let’s assume we want to protect not only the link between Node-A and Node-B but we also want to protect Node-B. Without TI-LFA, we can’t protect Node-B. According to formula it seems it isn’t possible …
