VPRN Service Configuration Commands
hold-time
Syntax hold-time seconds
no hold-time
Context config>service>vprn>bgp
config>service>vprn>bgp>group
Description
This command configures the BGP hold time, expressed in seconds.
The BGP hold time specifies the maximum time BGP waits between successive messages (either
keepalive or update) from its peer, before closing the connection. This configuration parameter can be
set at three levels: global level (applies to all peers), group level (applies to all peers in group) or
neighbor level (only applies to specified peer). The most specific value is used.
Even though the router OS implementation allows setting the keepalive time separately, the
configured keepalive timer is overridden by the hold-time value under the following circumstances:
The no form of the command used at the global level reverts to the default value.
The no form of the command used at the group level reverts to the value defined at the global level.
The no form of the command used at the neighbor level reverts to the value defined at the group level.
Default
90 seconds
Parameters

if the route resolving the BGP nexthop offers multiple nexthops.
The no form of the command resets the IBGP multipath feature to the default value (load-balance).
Default
ibgp-multipath load-balance

1. If the specified hold-time is less than the configured keepalive time, then the operational
keepalive time is set to a third of the hold-time; the configured keepalive time is not changed.
2. If the hold-time is set to zero, then the operational value of the keepalive time is set to zero; the
configured keepalive time is not changed. This means that the connection with the peer is up
permanently and no keepalive packets are sent to the peer.
connection to the peer is up permanently.
