BGP link bandwidth community

This feature facilitates the integration of devices with different transmission speeds within the network, enabling efficient traffic distribution based on link speed. BGP can communicate link speeds to remote peers, enabling better optimization of traffic distribution for load balancing. A BGP group can send the link-bandwidth non-transitive extended community over an EBGP session for originated or received and readvertised link-bandwidth extended communities. 

To configure the non-transitive link bandwidth extended community, include the bandwidth-nontransitive value in the export policy at the [edit policy-options community name members community-ids] hierarchy level. 

To enable the device to automatically detect and attach the link-bandwidth community on a route at import, include the link-bandwidth auto-sense statement at the [edit protocols bgp group] hierarchy level.
