Table 11: Inheritance from Other Commands (continued)
Inherits Global Values Set By Category B Command

bgp shutdown neighbor shutdown
bgp graceful-restart restart-time neighbor graceful-restart restart-time
bgp graceful-restart stalepaths-time neighbor graceful-restart
stalepaths-time
Example 1 For category A and B commands, the behavior of the no version of the command is
different from the behavior of the default version of the command. The no version
explicitly disables the feature:
•
Applied to a peer, the no version disables the feature regardless of whether the feature
is enabled for any peer group to which it belongs.
•
Applied to a peer group, the no version disables the feature regardless of whether the
feature is enabled for BGP globally or by default.
The default version simply unconfigures the feature for the peer or peer group.
•
Applied to a peer, the default version causes the peer to inherit the state of the feature
(enabled or disabled) from any peer group to which it belongs.
•
Applied to a peer group, the default version causes the peer group to inherit the state
of the feature (enabled or disabled) from the BGP global configuration.
The following example illustrates this difference and the inheritance concept with the
neighbor soft-reconfiguration inbound command.
host1(config-router)# neighbor lisbon peer-group
host1(config-router)# neighbor 10.19.7.8 peer-group lisbon
Inbound soft-reconfiguration is disabled by default, hence it is currently disabled for both
the lisbon peer group and peer 10.19.7.8.
host1(config-router)# neighbor lisbon soft-reconfiguration inbound
Inbound soft-reconfiguration is now enabled for the lisbon peer group. Because the peer
inherits values from the peer group, inbound soft-reconfiguration is now also enabled
for peer 10.19.7.8.
host1(config-router)# no neighbor 10.19.7.8 soft-reconfiguration inbound
The no command disables inbound soft-reconfiguration for peer 10.19.7.8, overriding the
configuration of the peer group to which the peer 10.19.7.8 belongs. The configuration of
an individual peer takes precedence over the configuration of the peer group to which
the peer belongs.
