In the network shown in the figure, OSPF runs between R1, R2, and R3. R1 and R3 use the loopback interface to establish an IBGP neighbor relationship, and the BFD function is enabled in the BGP process. The BFD parameters are "bfd min-tx-interval 1000 min-rx-interval 1000 detect-multiplier 6". If OSPF is disabled on R2’s GE0/0/1 interface through the "undo network xxxx yyyy" command, and the BGP neighbor relationship is checked on R1, by default, the longest time for the R1 BGP neighbor relationship to change from Up to Down is which of the following?
