A company has a BGP network and a BGP route of 196.27.125.0/24 that should be propagated toall of the devices. The route is not now in any of the routing tables.

What should be done topropagate this route?()A、Clear the BGP sessionB、Change both the inbound and outbound policy related to this routeC、Use the service-policy command to adjust the QOS policy to allow the route to propagateD、Use the release BGP routing command
考题
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
考题
A router has two paths to reach another network in a different autonomous system.

Which statement is true about how BGP would select the best path?()A、To influence one route to be preferred, its default local preference value will be changed via the use of the command bgp default local - preference 50B、Th e router will prefer the shortest autonomous system pathC、If the command bgp always - compare - med has been given, then the router will prefer the route with the highest MEDD、The router will prefer the route with the lower MED
考题
You work as a network engineer for the company, you want to configure two BGP speakers to form an EBGP session across a firewall. On the engineer’s network, the firewall always permits TCP sessions that are initiated from the inside network (the network attached to the inside interface of the firewall). What prerequisite is there for enabling BGP to run on this network?()A、EBGP multihop will need to be configured for this to work.B、This should work with normal BGP peering, with no additional configuration on the BGP speakers or the firewall.C、The BGP protocol port must be opened on the firewallD、There is no way to make BGP work across a firewall.
