Redistribute isis ip level-2 into level-1 route-map test Configured Areas: 1 Tunnel mpls traffic-eng path-option protect 10 explicit name R2R3R4 ! C 129 2.0.0.0/32 is subnetted, 1 subnets *Aug 18 11:26:02.546: Link state packet checksum This command only R3 on L2 routes redistributed into the OSPF , but R3 activated IS-IS is S0 / 0 direct port they will not be redistributed into 2 3.3.3.0 [115/20] via 10.1.123.3, FastEthernet0/0 10.0.0.0/24 is subnetted, 3 subnets Additional Knowledge: Label-to-label TTL diffusion behavior in SWAP , PUSH , POP operations Interface loopback1 2.2.2.2 HELLO message Or Tunnel Id ! Ip unnumbered Loopback0 Therefore, in the above figure, if R5 sends an IPv4 packet to R3 , R3 can directly identify and hash the source and destination addresses of the Ipv4 header to implement load balancing. RFC1195 LAN Priority: 64 Format: Phase V 10.1.12.2 Modify the configuration of R2 : Interface Ethernet0/1 ! The above command will add or subtract z from the original cost of the route ( the range of z is -10 to 10 ) Basic concept of FRR *Aug 18 09:06:02.699: Session Name: R1_t0 POP is the TTL of the top-level tag minus 1 and then pops up. The new TTL value is written to the top-level tag of the outbound data. Global Pool BW Unreserved: *Mar 1 00:00:32.755: ISIS-Upd: Building L1 LSP Mpls traffic-eng tunnels ip rsvp bandwidth *Aug 18 09:06:07.919: 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. Other features of the reserved tags between 0-15 are currently not defined. So our available tags are 16 to 1048575 ( 220-1 ) Mpls ldp neighbor 3.3.3.3 targeted ldp Router ospf 1 Router(config-if)# ip rsvp bandwidth ? Router-id 5.5.5.5 The TTL is placed in the label header. Turning off TTL propagation prevents the MPLS network from being exposed (by traceroute ). 0 packets, 0 bytes tag information set Next Hop Label space:Per-Platform Mpls traffic-eng tunnels ip rsvp bandwidth R3 Setting the priority and maintaining the priority all indicate whether a TE tunnel can preempt another TE tunnel by using the corresponding value . The lower the priority, the higher the importance. 1 byte defines NSEL . Therefore the NSAP address is at least 10 bytes. In the CISCO IOS in, the NSAP configured dotted 16 hexadecimal form. The AFI value of 49 can only be used locally, and is the reserved private address space defined by RFC1618 . 0 kbits/sec Traditional TTL operation RFC1195 NSEL is 00 ( 1B from the right ) The system ID is 0000.0c00.1111 The area ID is 39.0f01.0002 Network 10.1.23.2 0.0.0.0 area 0 mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 5.5.5.5/32 The implicit empty tag above has already been introduced, it does increase efficiency,ccna exam questions and answers pdf free download, but there is also a problem, because if I receive an implicit null tag sent by a downstream neighbor about a particular prefix bundle, then I am forwarding the tag. Before the data is given to the neighbor, I will first pop the top-level label. Then the pop-up action actually pops up the entire top-level label header, that is, even the fields with the label field, EXP, etc. pop up, and EXP knows For QoS , it is also popped up, meaning that some information for QoS is lost here .
