• ○

  Targeted sessions must exist between all routers in the tunnel's path.

• ○

  Each LDP interface must be configured to support LDP tunneling.

• ○

  LDP prefixes resolve to an RSVP LSP, rather than to a physical egress interface.

• ○

  RSVP LSPs must exist between each PE-ABR pair, or ABR-ABR pair in each area.

• ○

  Fast reroute requires you to manually define detour paths.

• ○

  Fast reroute provides path protection close to the failure point

• ○

  Fast reroute performs automatic path calculation and signaling.

• ○

  Fast reroute protects both primary and secondary paths.

• ○

  The path must include at least one hop.

• ○

  The path may be used multiple times in a single LSP.

• ○

  The path may comprise loose hop entries only.

• ○

  The path must define the LSP's tail end.

• ○

  The path may be used for multiple LSPs.

• ○

  Each PLR signals a detour LSP that avoids the downstream node. If the downstream node cannot be avoided, a detour LSP that avoids the downstream link is signaled.

• ○

  The detour LSP can take one or more hops before merging back on the protected LSP.

• ○

  The merge point of the protected LSP must be the next-next-hop node

• ○

  The ingress router will set the local protection desired flag in the session attribute object of the path message to inform all routers along the protected LSP path to establish detour LSPs.

• ○

  The label recording desired flag must be set in the session attribute object in order for the PLR to know what label to swap when using the detour LSP.

• ○

  Message-IDs replace individual refresh messages.

• ○

  Refresh reduction applies only to reservation messages.

• ○

  RSVP generates a summary-refresh message for each LSP.

• ○

  An LSP state change causes an incremented Message-ID.

• ○

  It supports IGP-based LSPs.

• ○

  It supports constrained path LSPs.

• ○

  It does not support loose explicit path LSPs.

• ○

  It is recommended for use in Traffic Engineering applications.

• ○

  It cannot be used with facility backup fast reroute.

  No primary path is established. The secondary path will take R1-R2-R4-R6.

• ○

  The primary path will take R1-R3-R5-R6. The secondary path will take R1-R2-R4-R6.

• ○

  The primary path will take R1-R2-R4-R6. No secondary path is established.

• ○

  The primary path will take R1-R2-R4-R6. The secondary path will take R1-R3-R5-R6.

• ○

  The LSP will go through the path R1-R2-R4-R6.

• ○

  The LSP will go through the path R1-R3-R5-R6.

• ○

  The LSP is down because router R1 detects that no path can meet its constraints.

• ○

  The LSP is down because router R4 detects that no path can meet its constraints.

• ○

  After a new path for LSP-1 is established on R1-R3-R5-R6, the old path is torn down.

• ○

  After the old path for LSP-1 is torn down, the new path is established on R1-R3-R5-R6.

• ○

  LSP-1 will stay on R1-R2-R4-R6 because there is enough bandwidth on the existing path.

• ○

  LSP-1 will be torn down because CSPF fails to find a new path.
