Set-overload-bit on-startup wait-for-bgp Debug isis update on R2 Priority 7 : 9375000 Link state Protocol Data Unit Link State Data Unit Backbone area Establish a target neighbor The forwarding of IP packets in each hop router is based only on the destination address. Network 10.1.23.2 0.0.0.0 area 0 Network 10.1.23.2 0.0.0.0 area 0 R5 and R6 each announce their own Loopback route in the BGP process.

When an ES wants to send a packet to another ES , it sends the packet to its directly connected network. !! Primary tunnel It was dismantled and then continued to be removed. 4.4.4.4/32 2.2.2.2 Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 The Level1 area is a collection of L1 routers and L1/L2routers , and Level2area is a collection of L2 routers and L1/L2 routers . No longer take the tunnel , and then go to traceroute 55.55.55.55 from R2 , no longer see the label. IIH *Aug 18 11:31:44.598: CLNP is similar to the IP protocol except that it serves the ISO transport layer. IS-IS , ES-IS , and CLNP are network layer protocols that are encapsulated directly in the data link layer frame. Compared with the OSPF packet in TCP/IP , it is hidden behind the IP header. The encapsulation efficiency of the former protocol packet is higher. During the ES-IS work process, the end system sends an ESH ( ES Hello ) message to a specific address to notify the router of its existence. The router listens to the ESH packet to discover the ES existing in the network , so that the packet arriving at the specific ES address is subsequently forwarded to the ES . In ES-IS , the router advertises its own existence to the ES by sending an ISH ( IS Hello ) message to a specific address . ES also monitor ISH , if a plurality of received IS transmitted ISH ,ccna vendor exam question answer, ES will then be selected, and sends all data to the IS .
