MPLS LDP-IGP synchronization configuration 1bit is the bottom of the stack (this position is 1 , the last label.

The 7th bit is an internal / external flag, set to 0 to indicate an internal metric, and 1 to be an external metric. The link ID can be the router ID of the neighbor .

Next Hop The tunnel 's build priority cannot be set higher than the hold priority. The configuration of R1 is as follows: Next, R1 calculates another alternative path to R7 through the existing information : R1-R2-R4-R5-R7 , this path passes CSPF ! The LSP carries the TLV for authentication. Device Internet segment 10.1.xy.0 / 24 , where xy is the device number, X small y large LSP tunnel is one-way Upon receipt of this PATH message, the tail router will return a RESV (reserved) message along the same path used by the PATH message, except that the direction is reversed. The RESV message contains the label that RSVP assigns to the tunnel . Next Hop The TCP/IP protocol stack, similar to ES-IS , is done by ARP , ICMP , and DHCP protocols in the TCP/IP stack . 10.1.23.3 [MPLS: Label 300 Exp 0] 108 msec 116 msec 64 msec Ip address 10.1.12.2 255.255.255.0 In all remote labels that bundle a particular prefix ,ccna help, the LSR uses only one of the labels to determine the outbound label for the prefix. RIB , which is the routing table, determines what the next hop of the IPv4 prefix is. The LSR selects the label of the next hop in the routing table that reaches the prefix from the remote label received by the downstream LSR . The LSR uses this information to create its own label forwarding information base, LFIB .
