ccna test format

The PATHTear packet is similar to the PATH except that it is sent when the TE tunnel LSP created by the headend router needs to be removed . For example, the tunnel interface is manually shut down . 0/0/0 *Aug 18 09:06:07.919: version=0 length in words=10 R3.00-00 Network 10.1.12.2 0.0.0.0 area 0 RFC2966 standardized from Level2 to Level1 leaked routes Link Sharing Detail: Fa0/0 Now the initial environment, R1 can learn inter-area routes, and R2 locally re - routes to level 1 route 2.2.2.0 . Of course, since R2 sets the attached-bit , R1 also generates a default route to R2 . Next hop 10.1.34.3, FastEthernet0/0 via 10.1.15.0/24 valid cached adjacency Set-overload-bit on-startup wait-for-bgp ! Related standards: R1#show mpls ldp neighbor The area address groups configured on the router are listed. It only appears in non-pseudo nodes Each ES belongs to a specific area,ccna test format, when the ES finds the nearest IS by listening to the HELLO ( ISH ) grouping of the intermediate system . Ability to send detail link information , including bandwidth . Replaces IS Neighbor TLV TLV 22 can contain 7 sub- TLVs , three of which contain bandwidth information for TE Router-id 3.3.3.3 Experimental verification Although the L1 / L2 router having both L1 and L2 function, but sometimes simply Establishing a specific interface on a layer adjacent relationship, are arranged on the other interfaces in the first 2 layers adjacent relationship. Therefore, in an NBMA network, such as a frame relay environment, it is strongly recommended to use the P2P sub-interface to run ISIS . !! Set MPLS TE routerID Ip address 10.1.12.1 255.255.255.0 55.55.55.55 [110/2] via 0.0.0.0, 00:00:01, Tunnel0 Type 2 length 36: Restrictions: Mpls traffic-eng tunnels mpls label range 100 199 Its ingress and exgress LSRs Outgoing Note: a L1 / L2 router if the other area router adjacency relationship, it will to this area of the L1 router advertisement himself outlet, the specific method is the raw cost region L1 LSP when packets ATT bit Set 1 The above command will add or subtract z from the original cost of the route ( the range of z is -10 to 10 ) How does a router know whether a message is a normal message or a label packet? MPLS packets are inserted between the Layer 2 header and the Layer 3 packet. Metric: 10 About LDP and IGP synchronization Certification Information ID: path option 10 [8] Ip cef RFC 2205 Resource Reservation Protocol (RSVP) ES-IS Attribute Flags: 0x00000000 Exit The CEF entry indicates that to go to 4.4.4.4 , the IP packet needs to be stamped with a value of 203 , and then the packet is dropped to the next hop 10.1.12.2 and thrown out from the Fa0/0 port. Router isis Two processes: neighbor discovery process, session establishment process Outgoing Lost LSPs can be requested by PSNP to see an example: Mpls traffic-eng tunnels mpls label range 500 599 Comment We open interface authentication between R1 and R2 : 8bit maximum 255 , usually in the labeling when it is the ordinary ip packet TTL direct copy came Net 49.0001.0000.0000.0002.00 Let's look at an example: The affinity attribute is a property that describes the MPLS TE tunnel and is also composed of 32 bits , which is exactly the same as the number of attribute-flags mentioned above . Also configured with the affinity attribute is a mask, also 32bits , which is used to match the attribute tag and the affinity attribute.
