Format

display bgp [ vpnv4 vpn-instance vpn-instance-name ] routing-table [ statistics ] dampened

display bgp ipv6 routing-table [ statistics ] dampened

display bgp vpnv6 vpn-instance vpn-instance-name routing-table [ statistics ] dampened (supported only by the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H)

display bgp vpnv4 { all | route-distinguisher route-distinguisher } routing-table [ statistics ] dampened (supported only by the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H)

Parameters

Parameter	Description	Value
vpnv4	Displays the BGP routes of a VPNv4 instance.	-
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	The value must be an existing VPN instance name.
statistics	Displays the statistics of dampened routes.	-
ipv6	Displays all dampened IPv6 routes.	-
vpnv6	Displays the BGP routes of a VPNv6 instance.	-
route-distinguisher route-distinguisher	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. A 4-byte AS number in dotted notation is in the format of x.y, where x 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.

Usage Guidelines

If the length of the destination address mask of an IPv4 route is the same as that of its natural mask, the mask length is not displayed after the command is run.
