RSVP Link connected to: a Stub Network RFC 2205 Resource Reservation Protocol (RSVP) In the dynamic setup, let the tunnel head end router calculate the path that the TE tunnel can traverse the network to the tail end in an optimal manner. We only need to configure the destination of the tunnel , and then the first-end router uses the CSPF algorithm to calculate the path itself. *Aug 18 04:37:06.239: min unit=0 bytes, max pkt size=2147483647 bytes ! The above figure encapsulates a three-layer label package. For an LSR , only the first label is processed. Each layer of the label has a bottom of the BoS stack to indicate whether it is already the bottom of the stack of the label,download ccna cisco, and the last label has BoS=1 .

ES-IS can be said to be a "language" or routing protocol between an end system and a router. It is used to enable the end system and router on the same network segment or link to discover each other and allow the ES to learn its network layer address.
