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