In general, BGP-4 requires that if a BGP speaker receives an OPEN message with an unrecognized optional parameter, the speaker must terminate BGP peering. This makes it difficult to introduce new capabilities into the protocol. The Capabilities parameter allows graceful negotiation of BGP capabilities without requiring a peer to terminate peering.

This command specifies use of the BGP Dynamic Capability feature, which allows dynamic update of capabilities over an established BGP session.

Use the set form of this command to specify dynamic update of BGP capabilities to be used in capability negotiation.

Use the delete form of this command to remove the dynamic update capability.

Use the show form of this command to view BGP neighbor configuration settings.
