Q247. Which of the following methods for route filtering are feasible?

By filtering routing protocol packets

By filtering routing information carried in routing protocol packets

For OSPF, route information calculated by filtering LSDB

For OSPF, pass Type 3 LSA

Q248. Regarding the Local_Preference attribute of BGP, the following statement is wrong ______

Local_Preferenc attribute is recognized and must be followed

The attribute value of Local_Preference only affects the traffic leaving the AS, not the traffic entering the AS

BGP router passes this attribute to IBGP neighbors

The BGP router passes the attribute to the EBGP neighbor

Q249. Assuming that router RTA receives a BGP route 10.10.10.0/24 from its iBGP neighbor without the AS_PATH attribute, how should RTA handle this BGP route?

Without the AS_PATH attribute, it indicates that this is a route originating from an autonomous system, and the BGP route is valid.

All routes learned from iBGP neighbors do not carry AS_PATH, this route is valid

The iBGP neighbor of the RTA is configured with the routing policy AS_PATH in the outbound direction, and the BGP route is valid

does not carry the AS_PATH attribute, the BGP route is invalid

NSAP is equivalent to the IP address and protocol number in the IP network. The same NSAP of the two systems will cause communication abnormalities

NSAP address includes three parts: area address, Stem ID and NSEL

The area address and Stem ID are fixed length, NSEL is variable length

Stem ID is used to identify IS in the area. In integrated IS-IS, it is recommended to be converted from the system’s Router ID or interface MAC address
