Ip access-list standard accept-ldp permit 1.1.1.1 The configuration of R1 is as follows: The TCP/IP protocol stack, similar to ES-IS , is done by ARP , ICMP , and DHCP protocols in the TCP/IP stack . TTL Network 10.1.45.4 0.0.0.0 area 0 NSAP can be understood as something like an IP+ port number. TOS 0 Metrics: 1 Select the path with the lowest IGP cost We spotted FIG, C for 30.0 / 24 bundled label prefix 0 , i.e. explicit null label, the label is then sent to map B , B also generates its own tag map is then sent to A . Then, at this time, if B receives a label packet from A and the value of the top label is 20 , then B finds its own LFIB and finds that the label is to be converted to 0 . Therefore,ccna r&s exam course download, B replaces the top-level label with 0 and then forwards it to C. At this time, for C , it receives a label packet with a label value of 0. C cannot forward the label value 0 in the LFIB . Message, because this tag value can be assigned to multiple FECs , C just pops up 0The tag is also an explicit null tag. After that, another search has to be performed. Although the search has to be performed twice, C can obtain the QoS information of the packet by looking at the EXP bit of the tag header .
