Which of the following descriptions about Frame Relay DLCI are correct? (multiple choice)

• A.On the same link, each virtual circuit is identified by a unique DLCI
• B.When the frame relay switching network transmits frame relay frames, it only changes its destination DLCI, that is, the value of the next hop DLCI, and does not change the value of the source DLCI of the sender
• C.The range of DLCI that users can use is 16~1007
• D.DLCI is used to identify a physical interface or logical interface on the router

The following routing information is seen on the MSR router running RIP:
<MSR>display ip routing-table 6.6.6.6
Routing Table: Public
Summary Count: 2
Destination/Mask Proto Pre Cost NextHop Interface
6.6.0/24 RIP 100 1 100.1.1.1 GE0/0
6.0.0.0/8 Static 60 0 100.1.1.1 GE0/0
At this time, the router receives a data packet with a destination address of 6.6.6.6, then ______.

• A.The packet will first match the static route in the routing table because its cost is low
• B.The packet will preferentially match the static route in the routing table because its mask is the shortest
• C.The packet will preferentially match the RIP route in the routing table because it has the longest mask
• D.The packet will match the RIP route in the routing table first, because of its high priority

On the MSR router, the -tos parameter of the ping command specifies the value of the ToS (Type of Service) field in the ICMP Echo Request message, the value range is 0~255, and the default value is ______.

• A.0
• B.46
• C.63
• D.2

The two routers MSR-1 and MSR-2 complete dynamic routing learning through RIP, and you can see the following debug information on MSR-1:
*Nov 26 02:20:25:353 2008 H3C RM/6/RMDEBUG: RIP 1: Sending v2 request on Serial 0/0 from 3.3.3.3
*Nov 26 02:20:25:353 2008 H3C RM/6/RMDEBUG: RIP 1: Sending request on interface Serial0/0 from 3.3.3.3 to 224.0.0.9
*Nov 26 02:20:25:400 2008 H3C RM/6/RMDEBUG: RIP 1: Receiving v2 request on Serial0/0 from 3.3.3.1
According to the debug information, ______ can be inferred. (Multiple choice)

• A.At this time, there is no RIP routing information from MSR-2 in the MSR-1 routing table
• B.It is possible that the RIP of the two routers has just started at this time
• C.At this time, there is already RIP routing information from MSR-2 in the MSR-1 routing table
• D.The RIP version between the two routers is inconsistent

An empty MSR router RTA connects two routers RTB and RTC running in OSPF Area 0 through GE0/0 and GE1/0 respectively. The IP addresses of the interfaces GE0/0 and GE1/0 of RTA are 192.168.3.2/24 and 192.168.4.2/24 respectively. Add the following configuration on RTA:
[MSR-ospf-1] area 0.0.0.0
[MSR-ospf-1-area-0.0.0.0]network 192.168.0 0.0.3.255
[MSR-GigabitEthernet0/0]ospf cost 2
[MSR-GigabitEthernet1/0]ospf dr-priority 0
Then the correct description of the above configuration is _____. (Multiple choice)

• A.Modifying the Cost of interface GE0/0 does not affect the establishment of OSPF adjacency
• B.RTA can only become the DR of the network segment where one of the GE interfaces is located
• C.RTA may become the DR of the network segment where the two GE interfaces are located
• D.This configuration only enables OSPF on the GE0/0 interface of the MSR router
• E.This configuration has enabled OSPF on GE0/0 and GE1/0 of the MSR router
