Relaxing RSVP Loop Checking

This draft proposes new rules for loop checking in networks, allowing an LSP to traverse a node multiple times with different interfaces and labels. It aims to enhance network connectivity and proposes updates to ERO/RRO handling. It does not introduce a new protocol. Future steps include considering alternative solutions and requesting draft adoption. Any questions are welcome.

  4. Solution • Relax loop checking as defined in RFC 3209 • New rules for loop checking • An LSP may pass through a node more than once. • Each pass through a node must use a different pair of inbound and outbound data interface and label. • Implementations may limit the number of passes. • ERO/RRO handling update to support this. • No new protocol is defined.

  5. Next Steps • Are there other solutions available? • Request adoption of draft. • Any Questions?
