Usage
Information
If the neighbor maximum-prefix is configured and the neighbor receives more
prefixes than allowed by the neighbor maximum-prefix command configuration, the
neighbor goes down and the show ip bgp summary command displays (prfxd) in
the State/PfxRcd column for that neighbor. The neighbor remains down until you
enter the clear ip bgp command for the neighbor or the peer group to which the
neighbor belongs or you enter neighbor shutdown and neighbor no shutdown
commands.

History
neighbor next-hop-self
c e s
Enables you to configure the router as the next hop for a BGP neighbor. (This
command is used for IBGP).
Syntax
neighbor {ip-address | peer-group-name} next-hop-self
To return to the default setting, use the no neighbor {ip-address | peer-group-name}
next-hop-self command.
ip-address
Enter the IP address of the neighbor in dotted decimal format.
peer-group-name
Enter the name of the peer group.
maximum
Enter a number as the maximum number of prefixes allowed for this BGP
router.
Range: 1 to 4294967295.
threshold
(OPTIONAL) Enter a number to be used as a percentage of the maximum
value. When the number of prefixes reaches this percentage of the
maximum value, the E-Series software sends a message.
Range: 1 to 100 percent.
Default: 75
warning-only
(OPTIONAL) Enter the keyword warning-only to set the router to send a
log message when the maximum value is reached. If this parameter is not
set, the router stops peering when the maximum number of prefixes is
reached.
