Q118. Regarding the first type of external routing and the second type of external routing in OSPF, the correct statement is ________

The first type of external routes are generated by injecting IGP routes

The first type of external routes are generated by injecting BGP routes

By default, the routes imported into the OSPF protocol through other routing protocols are all Type 2 external routes

If the routing information of the same network segment is learned through the first type of external routing and the second type of external routing at the same time, under the same other conditions, the first type of external routing information will be preferred

Q119. As shown in the figure, the MSR router of the headquarters is connected to the branch through the Ethernet interface E1/0, and the connection is backed up through the ISDN network.

Which of the following options are feasible at this time?

The RIP protocol runs on the Ethernet link between the headquarters and the branch. Then set the static route, the outgoing interface is Bri2/0, and the default priority value

OSPF protocol runs on the Ethernet link between the headquarters and the branch. Then set the static route, the outgoing interface is Bri2/0, and the priority value is 200

OSPF protocol runs on the Ethernet link between the headquarters and the branch. Then set the static route, the outgoing interface is Bri2/0, and the priority value is 0

The RIP protocol runs on the Ethernet link between the headquarters and the branch. Then set up a dynamic routing backup group on the outbound interface Bri2/0

Q120. In the topology shown in the figure, the following configurations are performed on RTA and RTB respectively:

Q122. E As shown in the figure, RTB and RTC each learn EBGP route N from RTD, RTB is missing LOCAL_PREF is set to 200, RTA and RTB, RTC establish IBGP neighbor relationship through loopback, RTA routing table, only N, RTB It is directly routed to the loopback of RTC and RTA itself. If RTB goes down due to a power failure, on RTA, can route N be switched to RTC immediately?

Yes, because the neighbor relationship between RTA and RTB is interrupted, RTA immediately switches to RTC

Yes, because the next hop of the route N pointing to RTB is unreachable, RTA immediately switches to RTC

No, because the neighbor relationship between RTA and RTB cannot be interrupted until the holdtime expires, and it takes about 3 minutes to switch over.

No, because RTA and RTB establish the IBGP neighbor relationship through the loopback address. If the interconnection interface is improved, it can be switched.
