The path attribute with its own AS number is not supported by
default.
Generally, the path attribute records the passed AS to prevent the
loopback of BGP routes. If the path attribute has its own AS num-
ber, it indicates the loopback happens and this route should be
invalid.
In the increasingly complex network applications, especially in the
MPLS-VPN HUB-SPOKE model application, it is likely that the route
has to pass some AS several times to meet the user's requirement.
This example describes how to enable the path attribute in the UP-
DATE message received from the BGP neighbor 1.1.1.1 to contain
four AS numbers of its own and the route is still effective.

neighbor default-originate

Use this command to make BGP send the default route to neigh-
bors or neighbor peers. Disable this function with the no form of
this command.
Router configuration and address family configuration
neighbor [<ipv4-address>|<ipv6-address>|<peer-group-nam
e>] default-originate
no neighbor [<ipv4-address>|<ipv6-address>|<peer-group-na
me>] default-originate
<ipv4-address>
<ipv6-address>

This command is disabled by default.
This command has BGP advertise the default route, no matter
whether there is local route.
This example describes how to send the default route to the BGP
neighbor 1.1.1.1.
