Remarks
By default, no route tag is
configured.
In some networks, a VPN might be
connected to multiple MCEs.
When one MCE advertise the
routes learned from BGP to the
VPN, the other MCEs might learn
the routes, resulting in routing
loops. To avoid such routing loops,
you can configure route tags for
VPN instances on an MCE. HP
recommends that you configure the
same route tag for the same VPN
on the MCEs.
By default, OSPF does not
redistribute routes from any other
routing protocol.
By default, OSPF does not
redistribute the default route.
This command redistributes the
default route in a Type-3 LSA. The
MCE advertises the default route to
the PE.
By default, OSPF does not filter
advertised routes.
The default cost is 1, the default tag
is 1, and the default type is Type-2.
By default, no OSPF area is
created.
Required
By default, an interface does not
run OSPF.
