AI Technical Summary
Technical Problem
Packets are discarded due to unicast reverse path forwarding (URPF) check failures when segment routing (SR) paths cross underlay networks in different routing domains, as the source IP address remains constant and is not reachable by the intermediate nodes.
Method used
Update the source and destination IP addresses of packets based on endpoint IP addresses assigned by the underlay network, eliminating the need for intermediate nodes to run IGP routing protocols and ensuring route reachability through operator-managed WAN interfaces.
Benefits of technology
Prevents packet discard by ensuring route reachability across multiple routing domains without relying on underlay network routing protocols, reducing overheads and maintaining packet integrity.
