Description
Extended gateway
data is not
exported because
there is no AS
information.
src_as and
src_peer_as are
zero because there
is no AS
information for
IGP.
Prior to Dell
Networking OS
version 7.8.1.0,
extended gateway
data is not
exported because
IP DA is not learned
via BGP.
Version 7.8.1.0
allows extended
gateway
information in
cases where the
source and
destination IP
addresses are
learned by different
routing protocols,
and for cases
where is source is
reachable over
ECMP.
Extended gateway
data is packed.
