# Execute the display ip routing-table command on Switch A. The output shows a static route entry with
interface Tunnel 3 as the output interface. (Details not shown.)
Manual bypass tunnel for FRR configuration example
Network requirements
On the primary CRLSP Switch A—Switch B—Switch C—Switch D, use FRR to protect the link Switch
B—Switch C.
Use RSVP-TE to establish the primary CRLSP and bypass tunnel of the MPLS TE tunnel based on the
constraints of the explicit paths. The bypass tunnel uses path Switch B—Switch E—Switch C. Switch B is
the PLR and Switch C is the MP.
Configure BFD for RSVP-TE between Switch B and Switch C. When the link between Switch B and Switch
C fails, BFD can detect the failure quickly and notify RSVP-TE of the failure, so RSVP-TE can switch traffic
to the bypass tunnel.
