! Insert ( impose or push ) IS-IS can route both CLNP and IP in mixed mode . 10 For TE of OSPF extension 75000 NNHop ( Next-Next Hop Router ): Next hop router, next hop of the PLR next hop router OSPF supports the following network types: P2P , broadcast, NBMA , point-to-multipoint, and on-demand circuits 75000 Designated IS ( DIS ) Access-list 100 deny udp any any eq 646 access-list 100 permit ip any any Experiment 2 Activate the MPLS TE extension for each router's OSPF and manually set the RouterID for MPLS TE . Router(config)#Ip cef 10.1.23.2 !! Cross-regional words must use loose next hop Bandwidth , latency , policy constrains The PATH message carries a label request object, which is hopped and hopped from the tunnel first-end router to the tail router. Mpls traffic-eng tunnels mpls label range 400 499 The boundary of the area is on the link ! Adjacent router R1#show mpls ldp neighbor 569 *Aug 18 04:37:06.239: Minimum Path Bandwidth (bytes/sec): 1250000 How labels are handled If there is a loop (usually a problem with the IGP , such as a misconfiguration of the static route), the TTL in the tag header will prevent the tag packet from being forwarded indefinitely. Tunnel mpls traffic-eng autoroute announce ! ! Router-id 4.4.4.4 ! 2.2.2.2/32 Remarks (Tunnel0) Destination: 4.4.4.4 Achieve reliability If the payload of the MPLS is an IPv6 packet, the load balancing is performed according to the source and destination addresses in the IPv6 header. According to different IS-IS PDU types and specific network environments,cisco pretest exam answers, the TLV ( Type/Length/Value ) field is immediately followed by various types of IS-IS PDUs . The PDU header and TLV fields form a complete IS-IS. PDU . In ISO10589 and RFC1195 these two current IS-IS standard, using the code ( code ) word, rather than the type ( type ), but since the TLV to other protocol standards, it TLV than CLV using multiple network literature Here we also use TVL instead of CLV . In IS-IS PDU variety used TLV , both ISO 10589 defined, there RFC 1195 defined.The TLVs defined in ISO are used in the CLNP network environment, but most of them are also used in IP network environments. The TLV defined in the RFC is only used in the IP environment. For an IS-IS PDU , you can carry a TLV that supports the CLNP protocol , and you can carry it.
