1

What is an AS Autonomous system also know as a routing domain?

network of interconnected routers and related systems managed under a common network

2

What is it called when BPG exchanges routes within an autonomous system?

Interior BGP (iBGP) session

3

What is it called when BPG exchanges routes between different autonomous system?

exterior BGP (eBGP) session

4

In distance vector routing protocol what is the vector?

Interface or direction to reach the network

5

In distance vector routing protocol what is the distance?

route metric to reach the network

6

Do distance vector routing protocols have a complete map of the whole network? yes or no

no

7

By default what does EIGRP advertise?

total path delay and minimum bandwidth for a route

8

What are OSPF advertisements called?

LSA Link State Advertisments

9

What does IS-IS use for advertisements?

LSP Link State Packets

10

In OSPF when a router receives an advertisement from a neighbor it stores the information where?

local database called Link State Database

11

What type of protocol is BGP?

Path Vector with BGP Path attributes

12

What is an example of longest prefix?

ex. /24 vs /28 - 28 is the longest prefix

13

If a routing protocol identifies multiple paths as the best path and supports multiple path entries, what does the router do?

What is this know as?

Installs the maximum number of paths allowed per destination

equal cost multi-path (ECMP) - also equal cost load balancing

14

What does ECMP provide?

Increase bandwidth across multiple paths by spitting the traffic equally across links

15

What are three types of static routes?

Directly attached
Recursive
Fully specific

16

What is a directly attached static route?

route that uses only the outbound next hop interface (uses interface not IP address)

17

What is a recursive static route?

specifies the IP address of the next-hop address (uses IP address not the interface)

18

What is a fully specified static route?

uses both an interface and next-hop IP address

19

What is a floating static route?

What is also configured on a floating static route?

it's used a backup route for connectivity

higher AD Administrative Distance

20

What is a Null static route?

Virtual interface that is always in a up state, that drop traffic and do not forward or receive network traffic

21

What does a VRF stand for?

What is used for?

Virtual Routing and Forwarding

Create separate virtual routers (routing tables) on a physical router
