A.PIM- There can be multiple C-BSRs in the SM domain, but only one BSR can be elected

B.BSR collects C-RP information from received C-RP packets

C.BSR floods the PIM with Bootstrap packets All routers in the SM domain advertise BSR information andC-RP information

D.OneC-BSR can also collect C-RP information from received C-RP packets

A.After the retransmission timer expires, the sender has not received the acknowledgment and will retransmit the unacknowledged data

B.The sender does not need to transmit the full window size of the message

C.Sliding window size can only increase or stay the same

D.The sender announces the initial window size

E.TCPSliding window allows multiple packets to be sent before an acknowledgment is received

F.The receiver needs to confirm the data packet of the sender

A.In the routing table, use"O_ The routing table entry identified by the ASE" identifier can only be learned through route import.

B.In the routing table, use "OSPThe routing table entry identified by the F" identifier can only be learned through Type 3 LSAs

C.In the routing table, useThe routing table entry identified by the "OSPF" identifier can be learned through the 1/2/3/5 type LSA

D.In the routing table, use "OSPThe routing table entry identified by the F" identifier can only pass through Type 1 LSAs

A.G0/0/2 of SW1 entersDiscarding state

B.G0/0/1 of SW2 entersDiscarding state

C.G0/0/2 of SW2 entersDiscarding state

D.No interface is blocked

E.G0/0/1 of SW1 entersDiscarding state

A.Support impo when BGP generates routes. There are two methods, rt and Network, and the Network method is more accurate.

B.By default, the default metric value of external routes imported by OSPF is 1, and the type of imported external routes is Type2.

C.ISIS level-2 netAfter the work route is imported to level-1, if the import policy is not manually configured, a routing loop will be formed.

D.Importing IBGP routes into OSPF may cause routing loops.
