 355
neighbor <1-16> timers hold-time <0, 3-65535>
Sets the period of time, in seconds, that will elapse before the peer session is torn down
because the switch hasn’t received a “keep alive” message from the peer. The default value is
180 seconds.
Command mode: Router BGP
neighbor <1-16> timers keep-alive <0, 1-21845>
Sets the keep-alive time for the specified peer, in seconds. The default value is 60 seconds.
Command mode: Router BGP
neighbor <1-16> advertisement-interval <1-65535>
Sets time, in seconds, between advertisements. The default value is 60 seconds.
Command mode: Router BGP
neighbor <1-16> retry-interval <1-65535>
Sets connection retry interval, in seconds. The default value is 120 seconds.
Command mode: Router BGP
neighbor <1-16> route-origination-interval <1-65535>
Sets the minimum time between route originations, in seconds. The default value is 15
seconds.
Command mode: Router BGP
neighbor <1-16> time-to-live <1-255>
Time-to-live (TTL) is a value in an IP packet that tells a network router whether or not the
packet has been in the network too long and should be discarded. TTL specifies a certain time
span in seconds that, when exhausted, would cause the packet to be discarded. The TTL is
determined by the number of router hops the packet is allowed before it must be discarded.
This command specifies the number of router hops that the IP packet can make. This value is
used to restrict the number of “hops” the advertisement makes. It is also used to support
multi-hops, which allow BGP peers to talk across a routed network. The default number is set
at 1.
Note: The TTL value is significant only to eBGP peers, for iBGP peers the TTL value in the
IP packets is always 255 (regardless of the configured value).
