The peer generate-link-bandwidth command configures the local device to obtain the link bandwidth of a specified directly connected EBGP peer and generate an extended community attribute.
The undo peer generate-link-bandwidth command cancels the existing configuration.
By default, the local device is disabled from obtaining the link bandwidth of a specified directly connected EBGP peer.
| Parameter | Description | Value |
|---|---|---|
| peerIpv4Addr |
Specifies the IPv4 address of a peer. |
The value is in dotted decimal notation. |
| peerIpv6Addr |
Specifies the IPv6 address of a peer. |
The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. |
| disable |
Disables a device to obtaining the bandwidth of directly connected EBGP neighbor interfaces. |

Usage Scenario
If you want to obtain the actual link bandwidth for load balancing and dynamically update the bandwidth when the actual bandwidth changes, run the peer generate-link-bandwidth command to obtain the link bandwidth of directly connected EBGP peers, generate extended community attributes, and update routing information.
After a peer is added to a peer group, if the peer group is enabled to obtain the link bandwidth of directly connected EBGP peers, the peer inherits the configuration of the peer group. If a peer does not need to inherit the configuration of its peer group, the peer must be disabled from obtaining the link bandwidth of its directly connected EBGP peer.Precautions
If the peer connect-interface, peer ebgp-max-hop, or ttl command is not run, you can run the peer generate-link-bandwidth command to obtain the link bandwidth of the directly connected EBGP peer.
