A default route A is configured on a MSR router running RIP, and its next hop address is 100.1.1.1. At the same time, the router learns from the neighbor router through RIP that a next hop address is also the default route of 100.1.1.1. B. The router uses the default priority and Cost values for the routing protocol, then .
A. There will be only route B in the router's routing table because dynamic routing takes precedence.
B. There is only route A in the routing table of the router because route A has a high priority.
C. In the routing table of the router, there is only route A, because the cost of route A is 0.
D. Both route A and route B are written to the routing table because they have different sources and do not conflict with each other.
Which of the following sources may be routed in the routing table of an MSR router?
A. Routing of directly connected network segments
B. Static route manually configured by the network administrator
C. Routes discovered by dynamic routing protocols
D. Routes discovered by the network layer protocol
See the routing table on an MSR router as follows:
|
Destination/Mask
|
Proto | Pre | Cost | NextHop | Interface |
| 6.6.6.0/24 | Static | 60 | 0 | 100.1.1.1 | GE0/0 |
| 8.8.8.8/32 | Direct | 0 | 0 | 127.0.0.1 | intloop0 |
| 20.1.1.0/24 | Static | 60 | 0 | 100.1.1.1 | GE0/0 |
| 30.0.0.0/8 | RIP | 100 | 1 | 100.1.1.1 |
GE0/0
|
Then the analysis of this routing table is correct.
A. The IP address of the interface GE0/0 on the router is 100.1.1.1.
B. The next hop of the route with the destination network segment being 8.8.8.8/32 is InLoop0, indicating that the next hop of the route is a virtual interface similar to Null0. The route belongs to the blackhole route.
C. The router is running RIPv1 because the mask of the destination segment 30.0.0.0 is a natural mask.
D. The routing table is not the complete routing table of the router. The complete routing table should have at least the direct network segment route of interface GE0/0.
The customer's network connection is like:
HostA----GE0/0--MSR-1--S1/0-----WAN-----S1/0--MSR-2--GE0/0----HostB
Both routers are factory default. The four interfaces of the router are configured with the correct IP address. The two hosts HostA and HostB are correctly configured with the IP address and gateway. Assume that all physical connections are normal. (choose one or more)
A. Each router must be configured with at least one static route to implement interworking between HostA and HostB.
B. Each router must be configured with at least 2 static routes to implement interworking between HostA and HostB.
C. No route is configured on the router. HostA can ping the IP address of interface S1/0 of MSR-2.
D. No route is configured on the router. HostA can ping the IP address of interface S1/0 of MSR-1.
The customer's network connection is like:
HostA----GE0/0--MSR-1--S1/0-----WAN----S1/0--MSR-2--GE0/0----HostB
The two MSR routers are interconnected through the WAN, and the physical connection is now normal. The S1/0 address of the MSR-1 interface is 3.3.3.1/30, and the S1/0 address of the MSR-2 interface is 3.3.3.2/30. The following four static routes are configured on the MSR-1:
| ip route-static 192.168.1.0 255.255.255.0 3.3.3.2 |
| ip route-static 192.168.2.0 255.255.255.0 3.3.3.2 |
| ip route-static 192.168.3.0 255.255.255.0 3.3.3.2 |
| ip route-static 192.168.4.0 255.255.255.0 3.3.3.2 |
The 192.168.0.0/22 subnet is the LAN user network segment of the MSR-2. So what are the errors described below? (choose one or more)
A. These four routes will be written to the routing table of MSR-1.
B. Only the fourth route will be written to the MSR-1 routing table.
C. These four routes can be replaced by a route ip route-static 192.168.1.0 255.255.252.0 3.3.3.2
D. Only the first route will be written to the MSR-1 routing table.
The following description of the route is correct. (choose one or more)
A. Route convergence means that the routes of routers in the entire network are consistently expressed.
B. A complete route must include at least the mask, destination address, and next hop.
C. The priority of the direct route cannot be manually modified.
D. IGP is a routing protocol based on D-V algorithm.
Which of the following statements is correct for RIPv1 and RIPv2 running on the MSR router? (choose one or more)
A. The route destination network segment learned on the RIPv1 router must be a natural classification network segment.
B. The route destination network segment learned on the RIPv2 router must be the subnet address of the variable length mask.
C. Both RIPv1 and RIPv2 can learn the route of the natural classification network segment.
D. Both RIPv1 and RIPv2 can learn routes of unnaturally classified network segments, such as routes with a destination network segment of 10.10.200.0/22.
See the following message on an MSR router running RIP:
<MSR>display rip
| Public VPN-instance name : |
| RIP process : 1 |
| RIP version : 2 |
| Preference : 100 |
| Checkzero : Enabled |
| Default-cost : 0 |
| Summary : Enabled |
| Hostroutes : Enabled |
| Maximum number of balanced paths : 8 |
Then from the display information can be analyzed.
A. The router is running RIPv2.
B. RIP's automatic aggregation function is turned on.
C. The cost of the RIP route sent or received by this router is 0.
D. Support 8 routes for load sharing
