If you have the two routers in the same area, can you use the distribute-list out command to filter resources between them

No to filter the routes use the command distribute-list in command not the distribute-list out. To filter networks received in updates, use the distribute-list in command in address family or router configuration mode. To change or cancel the filter, use the no form of this command. distribute-list [access-list-number | name] | [route-map map-tag] in [interface-type [...]

What are different types of stub areas in OSPF

OSPF relies on several types of Link State Advertisements (LSAs) to communicate link state information between neighbors. A brief review of the most applicable LSA types: Type 1 – Represents a router Type 2 – Represents the pseudonode (designated router) for a multiaccess link Type 3 – A network link summary (internal route) Type 4 – Represents an ASBR Type 5 – [...]

How are routing neighbours discovered in BGP

A BGP-speaking router does not discover another BGP-speaking device automatically. A network administrator usually manually configures the relationships between BGP-speaking routers. A BGP neighbor device is a BGP-speaking router that has an active TCP connection to another BGP-speaking device. This relationship between BGP devices is often referred to as a peer instead of neighbor because [...]

What is the concept of NLRI

BGP was designed to carry only unicast IPv4 routing information. BGP configuration used the Network Layer Reachability Information (NLRI) format CLI in Cisco IOS software. The NLRI format offers only limited support for multicast routing information and does not support multiple network layer protocols.

What are BGP path attribute

-Prefer the path with the highest WEIGHT. Note: WEIGHT is a Cisco-specific parameter. It is local to the router on which it is configured. -Prefer the path with the highest LOCAL_PREF. Note: A path without LOCAL_PREF is considered to have had the value set with the bgp default local-preferencecommand, or to have a value of [...]

Can you explain different OSPF packet types

Hello-Used to discover and maintain neighbours. Database Description-Used to form adjacencies. The router summarises all its linkstate advertisements and passes this information, via database description packets to the router it is forming an adjacency with Link State Request After the database description packets have been exchanged with a neighbour, the router may detect link state advertisements it requires to update [...]

What do the following statements in an extended access list accomplish?

Cisco routers use wildcard masking to identify how to check or ignore corresponding IP address bits. What does setting a wildcard mask bit to 0 cause the router to do?

Cisco routers use wildcard masking to identify how to check or ignore corresponding IP address bits. What does setting a wildcard mask bit to 0 cause the router to do? A. It tells the router to check the corresponding bit value. B. It tells the router to ignore the corresponding bit value. C. It tells [...]
