4. Advertise a default route to a
peer or peer group.

advertised.
Limiting routes received from a peer or peer group
This feature can prevent attacks that send a large number of BGP routes to the router.
If the number of routes received from a peer or peer group exceeds the upper limit, the router takes
one of the following actions based on your configuration:
• Tears down the BGP session to the peer or peer group and does not attempt to re-establish the
session.
• Continues to receive routes from the peer or peer group and generates a log message.
• Retains the session to the peer or peer group, but it discards excess routes and generates a log
message.
• Tears down the BGP session to the peer or peer group and, after a specified period of time,
re-establishes a BGP session to the peer or peer group.
You can specify a percentage threshold for the router to generate a log message. When the ratio of
the number of received routes to the maximum number reaches the percentage value, the router
generates a log message.
To limit routes that a router can receive from a peer or peer group (IPv4):

By default, the number of routes
that a router can receive from a
peer or peer group is not limited.
