As shown in the figure, for SWA, Eth0/2 belongs to VLAN 2, and Eth0/24 (PVID = 2) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through; for SWB, Eth0/2 belongs to VLAN 2, Eth0/3 belongs to VLAN 3, and Eth0/24 (PVID) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through. Which statement is true?
Answer(s): D
As shown in the figure, PE 1 sets up an MP-IBGP neighbor relationship with PE 2 and they communicate over MPLS LDP. A CE communicates with a PE over EBGP.Add two entries to the routing table of the VRF on PE 1:VRF1 RD 100:1, IRT 1:1, ERT 2:2VRF2 RD 100:2, IRT 1:1, 2:2, ERT 2:2, 3:3 Add two entries to the routing table of the VRF on PE 2:VRF1 RD 100:1, IRT 1:1, ERT 2:2VRF2 RD 100:2, IRT 2:2, ERT 1:1Import a valid static route 1.1.1.1/32 on CE 1. Suppose CE 2, CE 3, and CE 4 do not have route 1.1.1.1/32 in the local routing table. Which of the following routers have route 1.1.1.1/32 in the unicast routing table?
Answer(s): B,D
Refer to the exhibit.As shown in the figure, CE 1 and CE 3 belong to VPN A, CE 2 and CE 4 belong to VPN B, and users on different VPNs are not allowed to access each other. Which of the following configurations can enable mutual access between CE 1 and CE 4 but forbid cross-VPN access between other CEs?Configuration of PE 1:sysname PE 1#ip vpn-instance vpna route-distinguisher 100:1vpn-target 1:1 3:3 export-extcommunity vpn-target 1:1 3:3 import-extcommunity# i p vpn-instance vpnb route-distinguisher 100:2vpn-target 2:2 4:4 export-extcommunity vpn-target 2:2 4:4 import-extcommunity#Configuration of PE 2:#sysname PE 2#ip vpn-instance vpna route-distinguisher 200:1vpn-target 1:1 export-extcommunity vpn-target 1:1 import-extcommunity#ip vpn-instance vpnb route-distinguisher 200:2vpn-target 2:2 4:4 export-extcommunity vpn-target 2:2 4:4 import-extcommunity

Refer to the exhibit.Which statement about Hub & Spoke MPLS VPN is false?
Answer(s): B
Refer to the exhibit.As shown in the figure, PE 1 sets up an MP-IBGP neighbor relationship with PE 2 and they communicate over MPLS LDP. A CE communicates with a PE over OSPF.Configure the VRF on PE 1 as follows:ip vpn-instance vrf1route-distinguisher 100:1vpn-target 1:1 export-extcommunity vpn-target 1:1 import-extcommunityConfigure OSPF on PE 1 as follows:ospf 1 vpn-instance vrf1area 0.0.0.0network 100.1.1.0 0.0.0.255Configure BGP on PE 1 as follows:bgp 100peer 22.22.22.22 as-number 100peer 22.22.22.22 connect-interface LoopBack0#ipv4-family unicast undo synchronization peer 22.22.22.22 enable#ipv4-family vpnv4policy vpn-target peer 22.22.22.22 enable#ipv4-family vpn-instance vrf1import-route ospf 1PE 2 has the same configurations as PE 1. MP-IBGP neighbor relationships have been set up between PEs, and OSPF neighbor relationships have been set up between PEs and CEs. A valid route 1.1.1.1/32 is imported from CE 1 to an OSPF area, but CE 1 does not learn the route. What is the reason?
