In the network shown in the figure, IS-IS IPv6 runs between R2, R6, and R3, and the IPv6 address of R6 Looback0 interface is 2000::6/128.
Other links all run OSPFv3. Area 1 is a stub area and Area 2 is an NSSA area. IS-IS routes are imported into OSPFv3 on R2 and R3. Which of the following methods can enable R4 to ping
2000::6? (Multiple choice)

QUESTION NO: 2
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. 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 introduced into BGP through import. The maximum number of equal-cost routes configured for EBGP load sharing on R3 is 8.
By default, the number of equal-cost routes from R3 to 192.168.1.0/24 is which of the following?

In the network shown in the figure, R1 and R2 are configured with single-hop BFD detection. The network engineer found that the BFD session was Down, so he queried the configuration related to R1 and R2 BD. The configuration information has been marked in the figure. According to the configuration information, the reason for the BFD session Down is that the time parameters configured on R1 and R2 do not match.

QUESTION NO: 10
On a stable network that requires fast route convergence, you can change the value of the interval at which OSPF LSAs are updated to 0 so that topology or route changes can be immediately advertised on the network through LSAs, which speeds up route convergence.
