    > [TS]: Section 2.6 in RFC3209 describes a mechanism to determine whether a node should fragment or drop a packet that exceeds the Path MTU as discovered using RSVP signaling on primary LSP path. A PLR can leverage the RSVP discovered Path MTU on the backup and primary LSP path to ensure MTU is not exceeded after rerouting traffic on to the bypass tunnel.
    I think it'd be helpful to add a reference to that RFC and section here.
