Some of the commands in Table 10 on page 21 inherit global values set by other
commands. Table 11 on page 22 describes the relationship between these commands.
Table 11: Inheritance from Other Commands
Inherits Global Values Set By Category B Command
default-information originate neighbor default-originate
bgp graceful-restart neighbor graceful-restart
rib-out disable neighbor rib-out disable
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
