display ip routing-table [ verbose | | { begin | exclude | include } regular-expression ]

View

Any view

Parameter

verbose: Displays detailed routing table information, including that for inactive routes. With this argument absent, the command displays only summary information about active routes.

|: Uses a regular expression to filter output information.

begin: Displays routing table entries starting from the one specified by the regular expression.

include: Displays routing table entries specified by the regular expression.

exclude: Displays routing table entries other than those specified by the regular expression.

regular-expression: Regular expression, a string of 1 to 256 characters.

Table 1-1 Special characters for regular expressions

Character

Meaning

Remarks

_

Underscore, functions similarly as a wildcard and matches one of the following:

(^|$|[,(){}])

or a space, the beginning of a string, the end of a string.

If it is not the first character in a regular expression, it can appear as many times as the command line length permits.

If it is the first character in a regular expression, it can be followed with up to four underscores.

If it appears intermittently in a regular expression, only the first group takes effect.

(

Left parenthesis, represents a stack push operation in a program.

It is not recommended to use this character in a regular expression.

.

Full stop, a wildcard that matches any character, including a space.

*

Asterisk, indicates that the character(s) to its left can appear 0 or more times.

zo* matches z and zoo.

+

Plus, indicates that the character(s) to its left can appear one or more times.

zo+ matches zo and zoo, but not z.

1.1.3  display ip routing-table ip-address

Syntax

display ip routing-table ip-address [ mask-length | mask ] [ longer-match ] [ verbose ]

View

Any view

Parameter

ip-address: Destination IP address, in dotted decimal format.

mask-length: IP address mask length in the range 0 to 32.

mask: IP address mask in dotted decimal format.

longer-match: Displays the route with the longer mask.

verbose: Displays detailed routing table information, including that for inactive routes. With this argument absent, the command displays only summary information about active routes.

Description

Use the display ip routing-table ip-address command to display information about routes to a specified destination address.

Executing the command with different parameters yields different output:

l           display ip routing-table ip-address

The system ANDs the input destination IP address with the subnet mask in each route entry; and ANDs the destination IP address in each route entry with its corresponding subnet mask.

If the two operations yield the same result for an entry and this entry is active, it is displayed.

l           display ip routing-table ip-address mask

The system ANDs the input destination IP address with the input subnet mask; and ANDs the destination IP address in each route entry with the input subnet mask.

If the two operations yield the same result for an entry and the entry is active with a subnet mask less than or equal to the input subnet mask, the entry is displayed.

Only route entries that exactly match the input destination address and mask are displayed.

l           display ip routing-table ip-address longer-match

The system ANDs the input destination IP address with the subnet mask in each route entry; and ANDs the destination IP address in each route entry with its corresponding subnet mask.

If the two operations yield the same result for multiple entries that are active, the one with longest mask length is displayed.

l           display ip routing-table ip-address mask longer-match

The system ANDs the input destination IP address with the input subnet mask; and ANDs the destination IP address in each route entry with the input subnet mask.

If the two operations yield the same result for multiple entries with a mask less than or equal to the input subnet mask, the one that is active with longest mask length is displayed.

View

Any view

Parameter

ip-address1, ip-address2: Destination IP address, in dotted decimal notation. ip-address1/mask1 and ip-address2/mask2 combine to determine an address range. The system ANDs ip-address1 with mask1 for the starting address of the address range and ANDs ip-address2 with mask2 for the ending address of the address range.

mask1, mask2: IP address mask, address length in dotted decimal notation or expressed as an integer. When expressed as an integer, a mask takes a value ranging from 0 to 32.

verbose: Displays detailed routing table information, including that for both active and inactive routes. With this argument absent, the command displays summary information about active routes only.

Description

Use the display ip routing-table ip-address1 ip-address2 command to display information about the routes to the specified range of destination addresses.
