Question 101

As shown in the figure, MPLS/BGP IPVPN is deployed on the network.
The MP-BGP neighbor relationship is established between PE1 and PE2 through the LoopbackD interface.
After the configuration is complete, it is found that CE1 and CE2 cannot learn routes from each other.
Run the command to check the error on PE2.
The neighbor information is shown in the figure, what is the most likely cause of the problem?

A.PE1andPE2 not present BGP-VPN4 Enabling neighbors in unicast address family view

B.PE1orPE2± of VPN Instance parameter configuration error

C.PE1orPE2 with each other CEMisconfigu red routing protocol between

D.PE1andPE2 between LSPTunnel not established

Question 102

Regarding sham link, which of the following description is wrong?

A.The endpoint address of the sham link is advertised as a VPhv4 address by BGP. Routes that have passed sam1ik can also be imported into BGP in the form of VPNv4 routes

B.The sham link is a link between two VPN instances. Each VPN instance must have an endpoint address of the sham link, which must be a Loopback with a 32-bit mask in the VPN address space on the PE router. interface address

C.The sham link can be configured in any area and needs to be configured manually, and there must be a route to the sham link destination address (the sham link endpoint address of the peer PE) in the local VPN instance

D.In order to forward the VPN flow through the MPLS backbone network, the routing cost of the sham link should be less than the OSPF routing cost of the backdoor road
