Refer to the exhibit. A network administrator is troubleshooting a BGP adjacency issue between routers R2 and R5. R2 uses loopback0 interface 2.2.2.2 and R5 uses loopback0 interface 5.5.5.5 in the neighbor ip_address remote-as as_number statement in the configuration. However, an adjacency does not form. Which action can the administrator take to resolve the issue?. Add a static route on R5 to reach IP address 2.2.2.2. Issue the neighbor 5.5.5.5 remote-as 65501 command on R2. Add a default route on R2 toward R5. Ensure that the interface with IP address 10.1.45.5 is up/up.

(Choose two.). the default route being used to reach a neighbor. route filtering configuration. misconfigured timers. better source of information available. TCP port 179 being blocked by an ACL or a firewall.

Refer to the exhibit. A network administrator issues the show bgp ipv4 unicast | begin Network command to check the routes in the BGP table. What does the symbol ? at the end of a route indicate?. The route is originated from a connected network to the router. The route is learned through a static route. The route is the best route for the network prefix. The route is redistributed into BGP.

The AS number used in the neighbor configuration is wrong. The local router has no Layer 3 connectivity with the neighbor router.

Refer to the exhibit. A network administrator issues the show bgp ipv6 unicast | begin Network command on router R1 to verify routes in the IPv6 BGP table.

What are two reasons why all IBGP routers in a single AS must be in a full mesh topology? (Choose two.). IBGP routing requires fault tolerance provided by fully meshed connections. Transit traffic is not allowed within the AS where IBGP is used. An IBGP router does not prepend the ASN to the AS_Path attribute. An IGP provides fast convergence among IBGP routers.

Which two statements describe private BGP communities? (Choose two.). Private BGP communities are within the range of 0xFFFF0000 to 0xFFFFFFFF. An organization needs to register for a private BGP community. A private BGP community uses the first 16 bits to represent its AS and the second 16 bits to represent a pattern. Private BGP communities are used to signify no transit networks. A private BGP community requires a route map configuration.

A network administrator issues the show bgp ipv4 unicast summary command on a router to check the adjacency state with a neighbor router. The value under the State/PfxRcd field shows Active. Which statement describes the status of adjacency between the two routers?. The adjacency is successfully formed and routing prefixes are exchanged. Because the neighbor router has not responded to the open message, the adjacency is not formed. Because there is no Layer 3 connectivity between the two routers, the adjacency is not formed. The adjacency is successfully formed and the router is waiting for messages from the neighbor router.
