display bgp instance vpnv4 routing-table dampened

Function

The display bgp instance vpnv4 routing-table dampened command displays BGP dampened routes.

Format

display bgp instance bgpName vpnv4 { all | route-distinguisher rdValue } routing-table [ statistics ] dampened

Parameters

Parameter Description Value
bgpName

Specifies a BGP multi-instance.

The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

all

Displays all dampened BGP VPNv4 routes.

-

route-distinguisher rdValue

Displays the Route Distinguisher dampened BGP routes.

The RD formats are divided into the following types:

  • 2-byte AS number:4-byte user-defined number, for example, 101:3. An AS number ranges from 0 to 65535. A user-defined number ranges from 0 to 4294967295. The AS number and the user-defined number cannot be 0s at the same time. That is, an RD cannot be 0:0.
  • Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number ranges from 65536 to 4294967295. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0:0.4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0.
  • 4-byte AS number in dotted notation is in the format of x.y, wherex and y are integers that range from 0 to 65535 and from 0 to 65535, respectively. A user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot be both 0s. That is, an RD cannot be 0.0:0.
  • IPv4-address:2-byte user-defined number, for example, 192.168.122.15:1. An IP address ranges from 0.0.0.0 to 255.255.255.255. A user-defined number ranges from 0 to 65535.

Example

The actual command output varies according to the device. The command output here is only an example.
