Question 402

Off-stem cross-domain VPN-Option B scenario, the following description is incorrect?

During the packet forwarding process, it is necessary to exchange the VPN's private network LSP on the

two ASBRs IP-EBGP neighbor relationships.

The cross-domain VPN-Option B scheme is not limited by the number of interconnection links between ASBRs

The outer layer tag is exchanged between two ASBRs to vpnV4 routes.

Huawei's two switch SWA, SWB is connected together through 7 Ethernets, and static route aggregation is configured, and the corresponding ports on the switch SWA are E1/0/1, E1/02, E1/0/3, E1/0/4, E1/ 0/5, E1/0/6, E1/0/7, configured sequentially as if switch SWA, SWB Each aggregation group supports only 6 ports.

With the same configuration across ports, the Ethemet 1/0/7 port is the aggregate group Unselected port

With the same configuration of each port, the Ethemet 1/0/6 port is the aggregate group Unselected port

With the same configuration of each port, SWA randomly selects one of the 7 ports as the aggregate group Unselected port

With the same configuration of each port, the Ethemet1/0/1 port is the aggregation group Unselected port

Question 405

Router RL runs the OSPF protocol and uses the display ip routing-tabe command to view the router RL's routing table , the following information about OSPF in the routing table is described correctly as ?

In the routing table, the routing table entries identified by the OSPF identifier can only be learned through the 3 types of LSAs to

In the routing table, used The 'OSPF' identifier identifies a route table entry that can only pass a Type 1 LSA

In the routing table, the routing table entries identified with the 'OSPF identifier' can be learned through the 1/2/3/5 LSA to

In the routing table, Route table entries identified with the "O_ASE identifier can only be learned through routing introduction

Question 406

Regarding the BGP ring protection mechanism, the following description is correct?

A AS_PATH attribute is used between autonomous systems to prevent ring cats.

The Cluster List property is used for reflector cluster inner ring defense, and the router finds that the Cluster List of route entries contains its own Client lD The route is rejected

Routes learned from IBGP are not advertised to IBGP neighbors and are used to prevent routing loops inside the AS

You can use the AS_CONFED_SET attribute to prevent loops within a consortium:

Question 407

Regarding route Policy, the following description is correct as ?( Multiple selection) Multiple selection

Advanced ACLs can be applied in route-policy to filter routes

The table entry exceed::0 less-equal 128 indicates that all IPv6 routes are allowed through

If more than one node is defined in Route-policy, at least one node in each node should have a matching pattern of permit

Route-Policy can filter only the default route

Question 408

The correct description of the scene shown in the following figure is:

LSDB

R1, which exists in both Level-1 and Leve-2, can ping the interface address of R2 loopback0

R there is a route to R2 loopback0 10022/32

No neighbor relationship can be established between R1 and R2

Question 409

The following is the correct description of the aggregation of BGP (radio).

After you configure the Aggregate ipv4-address mask, only aggregate routes are published, not detail routes.

For IPv6 routing, BGP supports manual aggregation and automatic aggregation.

BGP enables automatic aggregation by default.

Routes in the BGP local route table can be manually aggregated.

Question 410

The following about BGP routing, describing the error, is ?

non-aggregate routes take precedence over aggregate routes

In PrefVal, Local_ Preference is equal to the case if the route is generated locally, IBGP Routing, the BGP preference for EBGP routing, is generated effectively referring to route priority.

See the following entry in the BGP routing table:* 172161.11/32 000010 0? Indicates that the route is available non-optimal

For next_hop unreachable routes when invalid routes, do not participate in the preferred.
