Routing Pt 2 Flashcards
What is the main objective of the IP Static Routing module?
Configure IPv4 and IPv6 static routes.
What command syntax is used to configure a static route?
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.
What are the types of static routes supported by IPv4 and IPv6?
- Standard static route
- Default static route
- Floating static route
- Summary static route
What command is used to configure an IPv4 default static route?
ip route 0.0.0.0 0.0.0.0 {<ip-address> | <exit-intf>}</exit-intf></ip-address>
What does a default static route represent?
A static route that matches all packets.
True or False: Directly connected static routes can be used with any interface type.
False
Directly connected static routes should only be used with point-to-point serial interfaces.
What is a fully specified static route?
A static route where both the exit interface and the next-hop IP address are specified.
What command is used to configure an IPv6 default static route?
ipv6 route ::/0 {<ipv6-address> | <exit-intf>}</exit-intf></ipv6-address>
What is a floating static route?
A backup static route that is only used when the primary route is unavailable.
What command verifies the configuration of static routes?
show ip route static
In a next-hop static route, what is specified?
Only the next-hop IP address.
What must be included when using an IPv6 link-local address as the next-hop address?
The interface type and interface number.
Fill in the blank: A __________ route is used when connecting an edge router to a service provider network.
default static
What does the command ‘show ipv6 route’ display?
The IPv6 routing table entries.
What is the recommended practice when configuring a static route on an Ethernet network?
Include a next-hop address.
What is indicated by an asterisk (*) next to a route in the routing table?
It indicates that the route is a candidate default route.
What is the purpose of the command ‘ping’ in the context of static routing?
To verify connectivity to a specific IP address.
What does the command ‘show running-config | section ip route’ do?
Displays the ip routes in the running configuration.
List the three types of static routes based on how the destination is specified.
- Next-hop route
- Directly connected static route
- Fully specified static route
What is the significance of the /0 mask in a default static route?
Indicates that none of the bits are required to match.
What does the command ‘ipv6 unicast-routing’ enable?
Enables IPv6 routing on the router and allowed configuration for ipv6 addresses.
What is a next-hop static route?
A static route where only the next-hop IP address is specified, and the exit interface is derived from the next hop.
When should directly connected static routes be used?
Only with point-to-point serial interfaces.
What is a default route?
A static route that matches all packets.
What is the command syntax for an IPv4 default static route?
ip route 0.0.0.0 0.0.0.0 {ip-address | exit-intf}
What is the command syntax for an IPv6 default static route?
ipv6 route ::/0 {ipv6-address | exit-intf}
What are floating static routes used for?
To provide a backup path to a primary static or dynamic route in the event of a link failure.
How is a floating static route configured?
With a higher administrative distance than the primary route.
What is the administrative distance of static routes by default?
1
What is a host route?
An IPv4 address with a 32-bit mask or an IPv6 address with a 128-bit mask.
How can a host route be added to the routing table?
Automatically installed, configured as a static host route, or obtained through other methods.
What is a local host route?
A host route automatically installed when an interface address is configured on the router.
What prefix length is used for IPv4 host routes?
/32
What prefix length is used for IPv6 host routes?
/128
True or False: A floating static route is used when the primary route is available.
False
Fill in the blank: The command to configure a default IPv6 static route is _______.
ipv6 route ::/0 {ipv6-address | exit-intf}
What does the ‘C’ in the routing table represent?
Connected network
What does the ‘L’ in the routing table output signify?
Local route with an ip address assigned to the interface
What happens if the primary route fails?
The floating static route becomes active.
What is the purpose of the distance argument in IP floating static routes?
To specify an administrative distance.
What is the significance of the ::/0 prefix in IPv6 routing?
It indicates that none of the bits are required to match.
What command is used to display the contents of the routing table for IPv6 static routes?
show ipv6 route static
