During BGP configuration on a router that has peered with other BGP speakers, the BGP command aggregate-a ddress 172.32.0.0 255.255.252.0 is issued. However, the peers do not receive this aggregate network in BGP advertisements. Also, the router does not have this aggregate network in its BGP table.Which option indicates a possible reason this command did not cause the router to advertise the aggregate network to its peers?（）A. Interface NULL 0 is likely shutdown.B. The next hop IP address must be a loopback address.C. The BGP command no auto - summary is missing.D. The BGP command no synchronization is missing.E. Subnets of 172.32.0.0/22 do not exist in the BGP table.F. The IGP running on this router does not have network 172.32.0.0/22 installed.
Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correctBGP session endpoint addresses and the correct BGP session hop-count limit EBGP multihop. What is agood first test to see if BGP will work across the firewall？（）A、Attempt to TELNET from the router connected to the inside of the firewall to the router connected to theoutside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transportdata.B、Ping from the router connected to the inside interface of the firewall to the router connected to theoutside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP totransport packets.C、There is no way to make BGP work across a firewall without special configuration， so there is no simpletest that will show you if BGP will work or not， other than trying to start the peering session.D、There is no way to make BGP work across a firewall.
In BGP routing，what does the rule of synchronization mean？（）A、A BGP router can only advertise an EBGP learned route，provided that the route is an IGP route in the routing table.B、A BGP router can only advertise an IBGP learned route，provided that the route is an IGP route in the routing table.C、A BGP router can only advertise an IBGP learned route，provided that the route is an IGP route that is not in the routing table.D、A BGP router can only advertise an EBGP learned route，provided that the route is a metric of 0 in the BGP table.
You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A、static route needs to be addedB、floating static route needs to be addedC、bgp backdoor commandD、ospf backdoor command
Refer to the exhibit. On the basis of the information in the exhibit， which two statements are true？（）A、When traffic is sent from the ISP to autonomous system 64512， the traffic will be forwarded toSanJose2 because of the higher MED value of SanJose2B、The serial 0/0/1 interface on the ISP router has been configured with the set metric 50commandC、The output was generated by entering the show ip bgp command on the SanJose1 routerD、The output was generated by entering the show ip bgp command on the ISP routerE、The serial 0/0/1 interface on the ISP router has been configured with the set metric 75commandF、When traffic is sent from the ISP to autonomous system 64512， the traffic will be forwarded toSanJose1 because of the lower MED value of SanJose1
When BGP is used as the PE-CE routing protocol, which of these statements is correct?（）A、On the CE router, PE neighbors must be configured in the VRF context on the CE routerB、On PE routers, the CE IBGP neighbors are configured in the global BGP configurationC、On PE routers, the CE EBGP neighbors are configured in the VRF contextD、A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router's other provider neighbors
