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
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.
S5000
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} update-source loopback interface command.
Parameters
ipv6-address Enter the IPv6 address in the x:x:x:x::x format.

fields of zeros.
