Router ospf 1 Local tag MPLS VPN Architecture CCSP Edition Ip address 3.3.3.3 255.255.255.0 ip router isis Prefix In front of the IP package. Then this 303 is actually the label assigned to the route of the next hop 10.1.15.0 of BGP route 5.5.5.5 . In other words, LDP does not assign labels to BGP routes, but assigns labels to the next hop (route) of BGP routes. Remote binding: tsr: 2.2.2.2:0, tag: 202 tib entry: 10.1.23.0/24, rev 12 For example, this CEF shows that the data going to 4.4.4.4 is stamped with 203 and then sent to 10.1.12.2 .

If a router does not recognize a TLV , it will be ignored. Oper: up *Aug 18 11:31:44.598: 5.5.5.5 OSPF MPLS label header. At the same time, the header of the Layer 2 data link layer will be instructed accordingly. For example, the Ethernet data frame, the TYPE field of the MAC layer indicates whether the upper layer data is an mpls label frame (if it is an IPv4 packet, the value is 0x0800 , if it is a label packet) Then it is 8847 -unicast or 8848- multicast) Ip address 1.1.1.1 255.255.255.255 !! Re-release the local direct loopback 2.2.2.0/24 to level1 Static mapping, when the network size is large, the configuration is surprisingly large. The enhanced features of IS-IS are defined in RFC 2763 , among which there is a mapping definition of dynamic host names. RFC 2763 introduces a new TLV ,ccna code 200 120, Type 137 , which is included in the LSP sent by the router participating in the dynamic mapping.

Regional association. The L1/L2 router sets this field in the L1 LSP it generates to notify the L1 routers in the same area to connect themselves to other areas. Usually, the L2 backbone area is connected. When the router in the L1 area receives the L1 LSP from which the ATT bit sent by the L1/2 router is set , it creates a default route to the L1/2 router so that data can be routed to other areas. Although the ATT bit is defined in both the L1 LSP and the L2 LSP , it will only be set in the L1 LSP , and only the L1/2 router will set this field.
