A. RSVP requests resource reservation

B. BGP MED?

C. from CE Layer 2 links

D. IP prefix

A. PIM is not enabled on the RPF interface

B. The router does not have an RPF route

C. Multi-router egress network, this router is not DR

D. The upstream router will receive the PIM Join message dropped

A. Sends an IGMPv2 membership report to the default router unicast of the local network

B. The IGMPV2 membership report is sent over multicast in the local network, and the destination multicast address of the IGMPv2 membership report is "All PIM Routers" 224002 Multicast address

C. The IGMPv2 membership report is sent over multicast in the local network, and the multicast address carried in the IGMPv2 membership report is the multicast address that you want to join

D. Sends a unicast IGMPv2 membership report to the RP

A. In addition to the 3 port states, RSTP vice adds 2 new port roles

B. If a port does not receive a configuration BPDU sent by the upstream device for 4 consecutive Hello Time, the device considers the negotiation with this neighbor to fail

C. RSTP port state specification is divided according to whether the port forwards user traffic and learns the MAC address, reducing the original 5 port states to 3

D. Non-root switches running RSTP send configuration BPDUs at intervals specified by Hello Timer, a behavior that is entirely autonomous for each device

A. Local PE sets up An Export Target for these routes before releasing VPNv4 routes learned from sites that are directly connected to them to other PEEs attributes, and are published with routes as extended community attributes for BGP.

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

C. By default, PE does not perform VPN-target filtering on received VPNv4 routes.

D. Carries the RD attribute when BGP publishes both reachable and unreachable VPNv4 routes.

A. The DHCP client receives an acknowledgment message from the server after it sends it

B. When a new host configured with an IP address is connected to the network

C. After the VRRP protocol master and standby role election is completed

D. When a host connected to the switch issues a Ping message.

A. By default, BGP routing rules can MED comparison of routes from different autonomous systems

B. By default, if there is no MED value in the route attribute, it is processed by 0 If the bestroute med-none-as-maximum command is configured, MED is processed as the maximum 4294967295

C. The default value for the BGP routing MED is 0

D. In the BGP routing rules, MED has a lower priority than AS Path, Praferred-value, Local-Preference, etc Origin

A. Reducing the minimum interval at which LSPs are sent per port can speed up the diffusion of LSPs.

B. The isP rapid diffusion feature, which first diffuses out LSPs that are smaller than a specified number, speeding up the synchronization process of LSDB

C. As link status information increases, the packet length of the LSP can be increased so that each ISP can carry more information.

D. By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes

A. When sending a neighbor request packet, the source address-is set as the link-local address

B. of the local interface Two types of ICMPv6 messages,

C. are used in the address resolution process, neighbor request and neighbor advertisement Address resolution implements the ability to resolve from IPv6 addresses to link-layer addresses

D. When sending a neighbor request packet, the destination address must be the multicast address of the neighbor's requested node

A. Can support running multiple instances on a single link

B. OSPFv3 message header will contain instance IDFu Duan flogging

C. Multiple instances can be run in the same OSPFv3 under the same interface

D. Under the sukugan of a shared router, each OSPFv3 process runs independently
