ipv6-address Enter the IPv6 address in the x:x:x:x::x format.

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.

Command Modes ROUTER BGP
Command History
Version 9.0(1.3) Introduced on the S5000.
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
• 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 S5000 software to use Loopback interfaces for TCP connections for BGP sessions.

To use the closest interface, use the no neighbor {ipv6-address | peer-
group-name} update-source loopback interface command.
Parameters
ipv6-address Enter the IPv6 address in the x:x:x:x::x format.
