Q

What command syntax is used to configure a static route?

A

ip route <network-address> <subnet-mask> {<ip-address> | <exit-intf>} [distance]</exit-intf></ip-address></subnet-mask></network-address>

This is for IPv4 routes; the syntax for IPv6 is similar.

Q

What is the purpose of the command ‘ping’ in the context of static routing?

A

To verify connectivity to a specific IP address.

18
Q

What does the command ‘show running-config | section ip route’ do?

A

Displays the ip routes in the running configuration.

19
Q

List the three types of static routes based on how the destination is specified.

A
  • Next-hop route
  • Directly connected static route
  • Fully specified static route
20
Q

What is the significance of the /0 mask in a default static route?

A

Indicates that none of the bits are required to match.

21
Q

What does the command ‘ipv6 unicast-routing’ enable?

A

Enables IPv6 routing on the router and allowed configuration for ipv6 addresses.

22
Q

What is a next-hop static route?

A

A static route where only the next-hop IP address is specified, and the exit interface is derived from the next hop.

23
Q

When should directly connected static routes be used?

A

Only with point-to-point serial interfaces.

24
Q

What is a default route?

A

A static route that matches all packets.

25
Q

What is the command syntax for an IPv4 default static route?

A

ip route 0.0.0.0 0.0.0.0 {ip-address | exit-intf}

26
Q

What is the command syntax for an IPv6 default static route?

A

ipv6 route ::/0 {ipv6-address | exit-intf}

27
Q

What are floating static routes used for?

A

To provide a backup path to a primary static or dynamic route in the event of a link failure.

28
Q

How is a floating static route configured?

A

With a higher administrative distance than the primary route.

29
Q

What is the administrative distance of static routes by default?

A

1

30
Q

What is a host route?

A

An IPv4 address with a 32-bit mask or an IPv6 address with a 128-bit mask.

31
Q

How can a host route be added to the routing table?

A

Automatically installed, configured as a static host route, or obtained through other methods.

32
Q

What is a local host route?

A

A host route automatically installed when an interface address is configured on the router.

33
Q

What prefix length is used for IPv4 host routes?

A

/32

34
Q

What prefix length is used for IPv6 host routes?

A

/128

35
Q

True or False: A floating static route is used when the primary route is available.

A

False

36
Q

Fill in the blank: The command to configure a default IPv6 static route is _______.

A

ipv6 route ::/0 {ipv6-address | exit-intf}

37
Q

What does the ‘C’ in the routing table represent?

A

Connected network

38
Q

What does the ‘L’ in the routing table output signify?

A

Local route with an ip address assigned to the interface

39
Q

What happens if the primary route fails?

A

The floating static route becomes active.

40
Q

What is the purpose of the distance argument in IP floating static routes?

A

To specify an administrative distance.

41
Q

What is the significance of the ::/0 prefix in IPv6 routing?

A

It indicates that none of the bits are required to match.

42
Q

What command is used to display the contents of the routing table for IPv6 static routes?

A

show ipv6 route static
