On Demand stub Routes BGP4+ , also known as Multiprotocol BGP , extends the BGP-4 specification to support new address clusters such as IPv6 , IPX , VPN, and more. Therefore, BGP4+ can carry routing information for IPv6 and other protocols including IPv4 . RFC2858 and RFC2545 defines the BGP4 + process IPv6 attributes updated.

At this time, the multicast data is actually going to R1, that is, to the receiver, but in fact, some more complicated things are still happening underneath. R1 receipt Register Thereafter, there will be formed the source wishes SPT , so it asks R2 issued a SPT of the join message, R2 after receiving own Fa0 / 0 is added to the corresponding port multicast table entry outgoing interface list of . However, since the multicast data is always sent from the Fa1/0 port of R2 (because when we tested, the specified outgoing interface is Fa1/0 ), R1 continuously receives the multicast data sent by R3 and encapsulates the multicast data. Register , but did not receive alongSPT passed down the multicast data,ccna 200 120 dumps pdf, therefore, Rl is not to R3 transmits Register-STOP , R3 registration process can be repeated, the multicast data will always be encapsulated in Register transmitted message Rl .
