1- At the Router> prompt, issue the enable command, and provide the required password when prompted.

The prompt changes to Router#, which indicates that the router is now in privileged mode.

2- Configure the FTP username and password.
R#config terminal
R(config)#ip ftp username test
R(config)#ip ftp password test
R(config)#end
R#

3- Copy the configuration to the FTP server.
R#copy running-config ftp:
Address or name of remote host []? N.N.N.N
Destination filename [R-confg]? backup
Writing backup !
1030 bytes copied in 3.341 secs (308 bytes/sec)
R#

Verification Commands

Common verification commands include the following:

show ip interface brief

show running-config interface interface-type number

show interfaces

show ip interface

show ip route

ping

In each case, replace ip with ipv6 for the IPv6 version of the command.

Filter Command Output

Filtering commands can be used to display specific sections of output. To enable the filtering command, enter a pipe (|) character after the show command and then enter a filtering parameter and a filtering expression.

The filtering parameters that can be configured after the pipe include:

section – This displays the entire section that starts with the filtering expression.

include – This includes all output lines that match the filtering expression.

exclude – This excludes all output lines that match the filtering expression.

begin – This displays all the output lines from a certain point, starting with the line that matches the filtering expression.

Note: Output filters can be used in combination with any show command.

Configure IP Default Static Routes

Default Static Route

•A default route is a static route that matches all packets. A single default route represents any network that is not in the routing table.

•Routers commonly use default routes that are either configured locally or learned from another router. The default route is used as the Gateway of Last Resort.

•Default static routes are commonly used when connecting an edge router to a service provider network, or a stub router (a router with only one upstream neighbor router).

•The figure shows a typical default static route scenario.

IPv4 Default Static Route: The command syntax for an IPv4 default static route is similar to any other IPv4 static route, except that the network address is 0.0.0.0 and the subnet mask is 0.0.0.0. The 0.0.0.0 0.0.0.0 in the route will match any network address.

Note: An IPv4 default static route is commonly referred to as a quad-zero route.

The basic command syntax for an IPv4 default static route is as follows:

Router(config)# ip route 0.0.0.0 0.0.0.0 {ip-address | exit-intf}

IPv6 Default Static Route: The command syntax for an IPv6 default static route is similar to any other IPv6 static route, except that the ipv6-prefix/prefix-length is ::/0, which matches all routes.

The basic command syntax for an IPv6 default static route is as follows:

Router(config)# ipv6 route ::/0 {ipv6-address | exit-intf}

Configure a Default Static Route

The example shows an IPv4 default static route configured on R1. With the configuration shown in the example, any packets not matching more specific route entries are forwarded to R2 at 172.16.2.2.

R1(config)# ip route 0.0.0.0 0.0.0.0 172.16.2.2

An IPv6 default static route is configured in similar fashion. With this configuration any packets not matching more specific IPv6 route entries are forwarded to R2 at 2001:db8:acad:2::2

R1(config)# ipv6 route ::/0 2001:db8:acad:2::2

Verify a Default Static Route

The show ip route static command output from R1 displays the contents of the static routes in the routing table. Note the asterisk (*) next to the route with code ‘S’. The asterisk indicates that this static route is a candidate default route, which is why it is selected as the Gateway of Last Resort.

Notice that the static default route configuration uses the /0 mask for IPv4 default routes. Remember that the IPv4 subnet mask in a routing table determines how many bits must match between the destination IP address of the packet and the route in the routing table. A /0 mask indicates that none of the bits are required to match. As long as a more specific match does not exist, the default static route matches all packets.

show ip route static

This example shows the show ipv6 route static command output to display the contents of the routing table.

Notice that the static default route configuration uses the ::/0 prefix for IPv6 default routes. Remember that the IPv6 prefix-length in a routing table determines how many bits must match between the destination IP address of the packet and the route in the routing table. A ::/0 prefix indicates that none of the bits are required to match. As long as a more specific match does not exist, the default static route matches all packets.

Static routes are commonly implemented on a network. This is true even when there is a dynamic routing protocol configured.

Static routes can be configured for IPv4 and IPv6. Both protocols support the following types of static routes:

•Standard static route

•Default static route

•Floating static route

•Summary static route

Static routes are configured using the ip route and ipv6 route global configuration commands.

Next-Hop Options

When configuring a static route, the next hop can be identified by an IP address, exit interface, or both. How the destination is specified creates one of the three following types of static route:

Next-hop route – Only the next-hop IP address is specified

Directly connected static route – Only the router exit interface is specified

Fully specified static route – The next-hop IP address and exit interface are specified

IPv4 Static Route Command

IPv4 static routes are configured using the following global configuration command:

Router(config)# ip route network-address subnet-mask { ip-address | exit-intf [ip-address]} [distance]

Note: Either the ip-addressexit-intf, or the ip-address and exit-intf parameters must be configured.

IPv6 Static Route Command

IPv6 static routes are configured using the following global configuration command:

Router(config)# ipv6 route ipv6-prefix/prefix-length {ipv6-address | exit-intf [ipv6-address]} [distance]

Most of parameters are identical to the IPv4 version of the command.

Troubleshoot IPv4 Static and Default Route Configuration

Network Changes

Networks fail for a number of reasons:

•An interface can fail

•A service provider drops a connection

•Links can become oversaturated

•An administrator may enter a wrong configuration.

Network administrators are responsible for pinpointing and solving the problem.

To efficiently find and solve these issues, it is advantageous to be intimately familiar with tools to help isolate routing problems quickly.

CommandDescription
ping•Verify Layer 3 connectivity to destination.
•Extended pings provide additional options.
