Step
5. (Optional.) Configure the type
code of an OSPFv3 extended
community attribute.
6. (Optional.) Configure an
external route tag for
redistributed VPN routes.
7. (Optional.) Disable setting the
DN bit in OSPFv3 LSAs.
8. (Optional.) Ignore the DN bit
in OSPFv3 LSAs.
9. (Optional.) Enable the
external route check feature
for OSPFv3 LSAs.
10. Return to system view.
11. Enter interface view.

Remarks
By default, the type codes for
domain ID, route type, and router
ID are hexadecimal numbers
0005, 0306, and 0107,
respectively.
Perform this configuration on the
PE.
By default, if BGP runs within an
MPLS backbone, and the BGP AS
number is not greater than 65535,
the first two octets of the external
route tag are 0xD000. The last two
octets are the local BGP AS
number. If the AS number is greater
than 65535, the external route tag
is 0.
Perform this configuration on the
PE.
By default, when a PE redistributes
BGP routes into OSPFv3 and
creates OSPFv3 LSAs, it sets the
DN bit for the LSAs.
Before using this command, make
sure it does not cause any routing
loops.
Perform this configuration on the
PE.
By default, the PE checks the DN bit
in OSPFv3 LSAs.
Before using this command, make
sure it does not cause any routing
loops.
Perform this configuration on the
PE.
By default, the PE checks the DN bit
in OSPFv3 LSAs to avoid routing
loops.
This command is compatible with
the old protocol (RFC 4577). HP
recommends not using this
command in the current software
version.
Perform this configuration on the
PE.
