Ipv6 nd prefix 2001:0001::/64 Command summary 5 Set next-hop specifies the address of the next hop , specifying the next hop of BGP . IPV6 and subnetting 00:00:27 2012::1 0xFFFF Dynamic routing protocol port number or protocol number Ipv6 address 2001::1/64 IPv6 has some special multicast addresses, which have special meanings. V1 uses broadcast, which is sent every 30s by default , using UDP port 520 (source, destination port) 1/128 Image The configuration of PE2 is as follows: Metric Client configuration The concept of traditional IP routing Let us review: When the router receives an IP packet, check the IP header of the packet, and take the destination IP of the packet to the routing table for comparison according to the longest matching principle. Finally, Forward the packet. Therefore, traditional IP routing can only be routed based on the purpose of the data. Image Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,ccna dump questions 2018, r RIB-failure, S Stale Image Phenomenon analysis: R3 directly generates multicast data. The source IP address of the multicast data is the interface IP address of R3 Fa0/0 , and the destination IP address is the multicast group address FF04::1 . These multicast data is sent directly to R2 . At this point, R2 is the First-hop router. Then when R2 received when the multicast data, because it is received in a multi-access network (in their Fa1 / 0 port), and their Fa1 / 0 port is free and not the LAN in the DR , since If it is not a DR , it has no right to initiate a register to the RP . Therefore, R2 simply creates an IPv6 group.
