BgpTrueFalseOrInherit
Whether or not the first AS number in the AS_PATH
attribute in an UPDATE received from this peer should be
checked to make sure it is the same as the AS number of
the peer. This flag only applies to EBGP peers. It
should be set to True unless the peer has a specific
policy that means it does not prepend its AS number so
that it is the first in the path.
When set to 'true', DC-BGP checks the first AS number in
UDPATES received from the peer.
When set to 'false', DC-BGP does not check the first AS
number in UDPATES received from the peer.
When set to 'inherit', the behavior for is determined by the
setting of the bgpRmEntCheckFirstAsNum field.
If a peer belongs to the peer group, then the peer's
configuration is taken from either this field or the
equivalent peer field, depending on the setting of the bit
in the bgpPeerConfigUsage field. The value for the peer
or peer group is determined and, if this is 'inherit',
then the bgpRmEntCheckFirstAsNum value is used.
This field can be changed at any time. However, if a peer
is configured to use the peer group field and the field is
changed while the peer is active, depending on the setting
of the bgpPeergrResetPeerOnCfgChange field, the peer
session may either be immediately reset, or the
configuration change is not applied until the peer session
is restarted.
