To return to the default values, use the no neighbor {ipv6-address | peer-group-name} timers command. Parameters ipv6-address Enter the IPv6 address in the x:x:x:x::x format. NOTE: The :: notation specifies successive hexadecimal fields of zeros. peer-group-name Enter the name of the peer group to set the timers for all routers within the peer group. keepalive Enter a number for the time interval, in seconds, between keepalive messages sent to the neighbor routers. The range is 1 to 65535. The default is 60 seconds. holdtime Enter a number for the time interval, in seconds, between the last keepalive message and declaring the router dead. The range is 3 to 65535. The default is 180 seconds. Defaults • keepalive = 60 seconds • holdtime = 180 seconds Command Modes ROUTER BGP Command History Version 9.9(0.0) 9.2(1.0) 8.2.1.0 7.4.1.0 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the E-Series ExaScale. Introduced Usage Information Timer values configured with the neighbor timers command override the timer values configured with the timers bgp command. When two neighbors, configured with different keepalive and holdtime values, negotiate for new values, the resulting values are as follows: • the lower of the holdtime values is the new holdtime value, and • whichever is the lower value; one-third of the new holdtime value, or the configured keepalive value is the new keepalive value. neighbor update-source Enable the software to use Loopback interfaces for TCP connections for BGP sessions. C9000 Series Syntax neighbor {ipv6-address | peer-group-name} update-source loopback interface To use the closest interface, use the no neighbor {ipv6-address | peer-group-name} updatesource loopback interface command.
