Bidirectional Forwarding Detection

Bidirectional Forwarding Detection (BFD) is a network protocol used to detect faults between two forwarding
engines connected by a link. BFD establishes a session between two endpoints over a particular link. If more
than one link exists between two systems, multiple BFD sessions may be established to monitor each one of

Description
Configures BGP routers that interconnect to
non-broadcast networks. Note that a remote AS
number must be specified for a neighbor before other
parameters can be configured.
Note: The advertisement-interval must be explicitly
configured for an address-family so that it can take
effect for that address-family. By default it will be
applicable only for the IPv4 address-family. Specify
the address family via the address-family command.
You can then set the neighbor advertisement-interval
in the address family configuration mode.
Specifies a network to announce via BGP.
Redistributes routes via BGP from another protocol
to BGP neighbors.
Overrides the configured router identifier and causes
BGP peers to reset.
Configures the BGP background scanner interval in
seconds. BGP monitors the next hop of the installed
routes to verify next-hop reachability and to select,
install, and validate the BGP best path. loops.
Configures BGP routing timers.
