5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide 11-66 neighbor maximum-prefix (IPv6 Address Family Config) This command specifies the maximum number of IPv6 prefixes that BGP will accept from a specified neighbor. The prefix limit is compared against the number of prefixes received from the neighbor, including prefixes that are rejected by inbound policy. If the peering session is shut down. the adjacency stays down until the "clear ip bgp" command is issued for the neighbor. The neighbor can also be brought back up using the "neighbor shutdown" command followed by the command no neighbor shutdown. Use the no command to revert to the default value for the maximum the number of prefixes that BGP will accept from a specified neighbor. neighbor ip-address maximum-prefix {maximum | unlimited} [threshold] [warning-only] no neighbor ip-address maximum-prefix Parameters ip-address maximum unlimited threshold warning-only The neighbor's IP 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 nct 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%. (Optional) If BGP receives more than the maximum number of prefixes, BGP accepts the excess prefixes and writes a log message rather than shutting down the adjacency. Default The default is Prefix Limit maximum number of supported routes in the forwarding table. The default warning threshold is 75%. Neighbors exceeding the limit is shutdown unless the warning-only option is onfigured. Command Mode IPv6 Address Family Config 11-67 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. Use the no command to disable the peer as the next hop for the locally originated paths. After executing this command,the BGP peer must be reset before the changes take effect. 1069
