In the network shown in the figure, OSPF protocol is run between R1, R2, and R3 . IBGP neighbor relationship is established between R1 and R3 using loopback interface. If OSPF is disabled on R2's GE0/0/1 interface through the "undo network xxxx yyyy" command, and BGP neighbor relationship is checked on R1, by default, the longest time for R1's BGP neighbor relationship to change from Up state to Down state is which of the following?

In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are imported into BGP. R3 configures the "peer yyyy as-path-filter 1 import" command for all neighbors. Which of the following can enable R3 to select the longest AS-Path to 192.168.1.0/24?

Which of the following is not a new addition to IS-IS to support IPv6 routing processing and calculation?
Which of the following is not a new addition to IS-IS to support IPv6 routing processing and calculation?A . TLV 236: describes the reachability of the network by defining routing information prefix, metric value and other informationB . TLV 232: It is equivalent to the "IP Interface Address" TLV in...
The service routes of an enterprise are transmitted in the network. The partial configurations of PE1 and PE2 are shown in the figure. At this time, CE1 adds a new service network segment and announces it to Area 1 of OSPF 10. In this scenario, which type of LSA will CE2 receive, which will contain the service network segment newly announced by CE1?
