Now 2001: 5555 :: 5 with VPNV6 label, but also the level of data is impenetrable MPLS BACKBONE , because the P routers do not recognize this tag. Therefore, it is necessary to add another tag so that the intranet tag and data payload can be transmitted in the MPLS BACKBONE . This outer label is assigned by LDP . Mpls ip Double-point bidirectional routing re-release Interface Serial0/0 ipv6 enable Further, it is found that P is 430.4.4.4 , the label 301 is allocated . Therefore, when PE1 receives the data packet and goes to 2001:5555::5 , the data packet is pressed into two layers, and the outer label value is 301 , the inner label value is 403 . IPv4- compatible addresses are used for transition mechanisms such as automatic ipv4- compatible tunneling and NAT-PT (see the IPv6 Transition Technology section of this document for details). Ipv6 address 2002:CA65:C01 ::FFFF/64 ipv6 enable 1/16 Ipv6 address 2002.c058.6301::/128 anycast tunnel mode ipv6ip 6to4 Route-target export 234:4 Foundation Ipv6 address 2002:CA65:C01 ::FFFF/64 ipv6 enable !! xxx is validtime , yyy is prefered time , this is absolute time The router bit indicates whether it is a router or not. If it is 0 , the announcer cannot route data. The way through the announcer Prefix announcements are the initial mechanism for stateless autoconfiguration. Using RA ( ICMPv6 Type 134 ) and the multicast address of all nodes ( FF02::1 ), the router RA message is periodically sent to FF02::1 on the local link . The router is typically used to determine whether the inbound interface and the source and destination address type CEF exchange . For consider CEF of routers , the outbound interface must be configured to CEF exchange mode , if the interface is configured CEF, then CEF will attempt to exchange data package. Otherwise , CEF will deliver the packet to the next best available exchange method. Image Route redirection Interface loopback0 ipv6 enable 64bits interface identifier address, constitutes 128bits of IPv6 global unicast address, and it will generate a default route to the ISATAP Modify the TAG of all external LSAs generated by the ASBR . None Hash None uses the distribution list or the access control list deny 521 port. Improve The configuration of R1 is as follows: Now, we have to go through the calculations to get a summary of the segments that are just "inclusive". The primary purpose of PMTUD is to discover the MTU on the path and avoid fragmentation as the packet is forwarded from the source to the destination. Dependent on the PMTUD source node can communicate with the destination node using the largest PMTU found , which can avoid the packet being fragmented by the midway router during the process of transmitting from the source to the destination,ccna exam test online, resulting in performance degradation.
