By default the prefix limit is set to the maximum number of routes that can be installed in the forwarding

table. The default warning threshold is 75%. A neighbor that exceeds the limit is shutdown unless the

warning-only option is configured.

neighbor ip-address maximum-prefix {maximum | unlimited [threshold]

[warning-only]

IPv6 Address Family Config

The neighbor's IPv6 address.

The maximum number of prefixes BGP will accept from this neighbor. Range is 0 to the maximum

number of routes the router supports.

Do not enforce any prefix limit.

(Optional) When the number of prefixes received from the neighbor exceeds this percentage of the

maximum, BGP writes a log message. The range is 1 to 100 percent. The default is 75%.

warning-only

(Optional) If BGP receives more than the maximum number of prefixes, BGP discards excess

prefixes and writes a log message rather than shutting down the adjacency.

no neighbor maximum-prefix (IPv6 Address Family Config)

This command reverts to the default value for the maximum the number of prefixes that BGP

will accept from a specified neighbor.

no neighbor ip-address maximum-prefix

IPv6 Address Family Config

neighbor next-hop-self (BGP Router Config)

This command configures BGP to set the next hop attribute to a local IP address when

advertising a route to an internal peer. Normally, BGP would retain the next hop attribute

received from the external peer.

When the next hop attribute in routes from external peers is retained, internal peers must

have a route to the external peer's IP address. This is commonly done by configuring the IGP

on the border router to advertise the external (or DMZ) subnet. The next-hop-self option

eliminates the need to advertise the external subnet in the IGP.
