Each bit can represent an attribute of the link (such as whether it is encrypted or not) or a managed policy. There is no specific syntax for this 32bits . Each bit can be set to the latter without moving it. The network designer can think of specifying a specific meaning for a particular bit as needed . *Aug 18 09:06:07.919: version:1 flags:0000 cksum:0000 ttl:255 reserved:0 length:232 In a network running MPLS , you can set these two paths to different LSPs and use different labels.

BGP routing entry is pretty much, by this way we MPLS , can greatly simplify the performance loss routers, BGP 's Transit AS routing black hole problem has been solved. Pop tag The TLVs used are: Nterface Interface FastEthernet0/0 RFC 2763 1178 LDP non-directly connected neighbors Router-id 1.1.1.1 Router ospf 1 The configuration of R3 is as follows: NLPID: C Physical_bw: 100000 (kbps), max_reservable_bw_global: 75000 (kbps) There are two types of tunnel priorities: 1.1.1.1 The Address Interface IPv6 : type value 232 ( 0xE8 ), which corresponds to the IPv4 in " the IP Interface the Address" TLV , but the original 32 -bit IPv4 address to the 128 -bit IPv6 address. We see that the main content of the pseudo-node LSP is the IS connected to this pseudo-node .

If it does not exist, the receiving router creates a new adjacency relationship, which is set to "initialization" state, and the system type is "unknown". The IIH response is then sent . If the router receives an IIH packet from the new neighbor , the router sets the adjacency to UP and the system type is IS . However, there is a problem here. After the local IIH is sent, I don’t know if the other party is If it is received, then there is a possibility that the message will be lost in the middle and the UP side will be DOWN . So we introduced a three-way handshake mechanism, see below.
