DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} maximum-prefix MAXIMUM [THRESHOLD] [warning-only] no neighbor {IP-ADDRESS | IPV6-ADDRESS | PEER-GROUP-NAME} maximum-prefix Parameters IP-ADDRESS IPV6-ADDRESS PEER-GROUP-NAME MAXIMUM THRESHOLD warning-only Specifies the IP address of the neighbor. Specifies the IPv6 address of the neighboring peer. Specifies the name of a Border Gateway Protocol (BGP) peer group. Specifies the maximum number of prefixes acceptable from the specified neighbor. When the command is used in the IPv4 Unicast or IPv4 Multicast Address Family Configuration mode, this value must be between 1 and 16384. When the command is used in the IPv6 Unicast Address Family Configuration mode, this value must be between 1 and 7168. (Optional) Specifies the percentage of the maximum prefix limit to generate a warning message. The range is from 1 to 100. The default value is 75. (Optional) Specifies only to generate a system log message when the threshold is exceeded. If not specified, the peering session will be terminated when the threshold is exceeded. Default By default, the maximum number of prefix value is 16384. (IPv4 Unicast or IPv4 Multicast Address Family Configuration Mode) By default, the maximum number of prefix value is 7168. (IPv6 Unicast Address Family Configuration Mode) The threshold value is 75 percent. Command Mode Router Configuration Mode. Address Family Configuration Mode (IPv4 Unicast, IPv6 Unicast, and VRF). Address Family Configuration Mode (IPv4 Multicast, L2VPN VPLS and VPNv4). (MI Mode Only) Command Default Level Level: 12. Usage Guideline The user can use the maximum-prefix command to configure a maximum number to restrict the number of routing prefixes that can be accepted from the specified peer. To use the command, the user should determine the maximum number of prefixes based on the amount of available system resources. When the maximum number is defined for a session, the system will monitor whether the current prefix number exceed the threshold. When the threshold is exceeded, if the option warning-only is not specified, the session will be terminated and a system message will be generated to notify the user of the event. If the warning-only option is specified, a system message will be generated to notify the user of the event. If a session is terminated due to exceeding of the maximum prefixes, the session will not be rebuilt unless the clear ip bgp command is issued to do a hard reset on the session. 223
