The routing protocol in the IP network forwards the data packet according to the minimum metric principle. With BDR , the DR cannot be preempted, and the DR sends Hello at the normal frequency. 75000 Tunnel mpls traffic-eng path-option 10 dynamic Adjacency Run OSPF on the entire network to announce direct connection and loopback interface. MPLS VPN configuration Both use a similar mechanism for routing information exchange, namely diffusion For Layer 2 link layer encapsulation, it can be all package types supported by CISCO IOS , PPP , HDLC , Ethernet, and so on. Then in the header of these Layer 2 , it is necessary to have a corresponding protocol field to indicate that the upper layer is a label header. Router(config)#mpls traffic-eng reoptimize timers frequency ? A pseudonode represents a broadcast multi-access network (including all ISs connected to this LAN ), which actually "as a router" (above, gray router) in the network. In other places, this is a whole. So does this whole have to generate an LSP ? This LSP is generated by the DIS . 0x1B7C Interface Loopback0 10.1.12.2 [MPLS: Label 201 Exp 0] 132 msec 184 msec 88 msec 75000 State: dynamic path option 10 is active 75000 kbits/sec, 3.3.3.3/32 For MPLS TE of the LSA Type 2 length 36: 103 Pop tag 0/0/0 Reservable Bandwidth[2]: 5.5.5.5 [110/31] via 10.1.23.3, 00:02:29, Ethernet0/1 ! Configured on L1/L2 rouer,ccna exam questions and answers pdf, which is R2 , a default route is generated and flooded to R3 , but not to R1 . LS age: 705 Commonalities: Configure the tunnel interface. Next, on the headend LSR , the path calculation PLALC or the restricted SPF ( CSPF ) algorithm can calculate the shortest, all conditions, from the head end LSR to the tail end according to the MPLS TE database mentioned above and the requirements of the tunnel . The path to the LSR . After the completion of the work output is from a tunnel end to a trailing end of the first IP address of the sequence, the guide path . PCALC and CSPF are variants of an SPF algorithm for MPLS TE .
