Q

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?

A

Installs the maximum number of paths allowed per destination

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

Q

What is a directly attached static route?

A

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

17
Q

What is a recursive static route?

A

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

18
Q

What is a fully specified static route?

A

uses both an interface and next-hop IP address

19
Q

What is a floating static route?

What is also configured on a floating static route?

A

it’s used a backup route for connectivity

higher AD Administrative Distance

20
Q

What is a Null static route?

A

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

21
Q

What does a VRF stand for?

What is used for?

A

Virtual Routing and Forwarding

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