8.16 Configuring a BGP Device to Send a Default Route to
Its Peer
After a BGP device is configured to send a default route to its peer, the BGP device sends a
default route with the local address as the next-hop address to a specified peer, regardless of
whether there are default routes in the local routing table. This greatly reduces the number of
routes on the network.
Issue 02 (2014-09-30)
Run the display bgp routing-table dampening parameter command to check configured
BGP route dampening parameters.
