Neighbor Update-Source - Dell N1100-ON Reference Manual

• keepalive—The time, in seconds, between BGP KEEPALIVE packets sent
to a neighbor. The range is 0 to 65,535 seconds. A small internal jitter is
applied to the keepalive interval timer in order to reduce the CPU load
that may occur when multiple timers expire simultaneously.
• holdtime—The time, in seconds, that BGP continues to consider a
neighbor to be alive without receiving a BGP KEEPALIVE or UPDATE
packet from the neighbor. If no KEEPALIVE is received from a neighbor
for longer than the hold time, BGP drops the adjacency. If the hold time is
set to 0, then BGP does not enforce a hold time and BGP does not send
periodic KEEPALIVE messages. The range is 0, 3 to 65,535 seconds.
Default Configuration
The keepalive and hold timers default to the globally configured values set
with the timers bgp command.
Command Mode
BGP Router Configuration mode, IPv4 Address Family Configuration mode
User Guidelines
The new values are not applied to adjacencies already in the ESTABLISHED
state. Updated keepalive or hold time values are only applied when an
adjacency is newly formed.

neighbor update-source

The neighbor update-source command configures BGP to use a specific IP
address as the source address for the TCP connection with a neighbor. This IP
address must be the IP address configured on the peer BGP router as the
neighbor address for this router.
