B. By default, the default metric of the external route redistributed by OSPF is 1, and the imported external route type is Type2.

C. Introducing IBGP routes in OSPF may cause routing loops.

D. After the ISIS level-2 network route is imported to the level-1 route, the routing loop is formed if the import policy is not manually configured.

A. The second layer gateway of VXLAN allows tenant access XLAN, and used to communicate between the subnets in the same VLAN.

B. The third layer gateway of VXLAN can be divided into centralized gateway and distributed gateway.

C. The third layer gateway of VXLAN allows inter-subnet VXLAN communications and external network access.

D. VXLAN Layer 2 gateway is bound to the VPN instance.

A. ACL

B. Regular expression

C. AS-path-filter

D. IP-prefix

A. All entries are removed (purged).

B. All entries are removed except for those behind edge ports and the port where TC was received.

C. Only entries behind the port where TC was received are removed.

D. All entries are removed except for entries behind edge ports.

E. The aging timer is set to 15 seconds, so idle entries age out.

A. The first responder with a response timeout sends Report message, and the other recipients do not send it.

B. Only when IGMPv1 is running, all receivers respond to the Report message.

C. Only the IGMPV2 is running, and all receivers respond to the Report message.

D. All recipients will respond to the Report message.

A. An MP-EBGP neighbor relationship needs to be established between the two ASBRs.

B. The inter-domain VPN-option-B scheme is not limited by the number of interconnection links between ASBRs.

C. Exchange the outer label of the VPNv4 route between the two ASBRs.

D. During the packet forwarding process, the private network LSPs of the VPN are exchanged on the two ASBRs.

A. Before the local PE advertises the VPNv4 route learned from the site directly connected to itself to other PEs, it sets the Target attribute for these routes and advertises it as a BGP extended community attribute along with the route.

B. When BGP advertises reachable and unreachable VPNv4 routes, it carries the RD attribute.

C. The VPNv4 address has a total of 12 bytes, including an 8-word route identifier RD (Route Distinguisher) and a 4-byte IPv4 address prefix.

D. By default, the PE does not perform vpn-target filtering on the received VPNv4 routes.

A. If the R2 Ethernet 0/0/1 interface is down, the next hop of the route that R1 reaches 10.0.0.2 is changed to 10.0.12.2.

B. The OSPF status changes to FULL, which triggers the BFD session.

C. If the R2 Ethernet0/0/0 interface is down, the next hop of the route that R1 reaches 10.0.0.2 is changed to 10.0.21.2.

D. If the R2 Ethernet 0/0/1 interface is down, the R1 BFD session can quickly detect the fault and notify R1 to make the OSPF neighbor relationship down.

E. If the BFD function is disabled on R2, the BFD session of R1 will be down. It will cause OSPF neighbor relationship down.

A. TRUE

B. FALSE
