Autonomous System (AS) is a number of grup
Address IP operated by one or more network which
have same eksternal policy routing. Eksterior Routing
Protocol used to transfer of routing information
between AS Number.
2. WHEN AUTONOMOUS SYSTEM NEEDED?
AS needed if a network incircuit to more than 1
AS where have different Routing Policy. Most example often met is: network which incircuit to two upstream
or more and or eXchange Point, peering with local network
in Point eXchange.
3. WHAT IS AUTONOMOUS SYSTEM
NUMBER?
A AS Public which have unique numbering (different)
called as AS Number.
This number function at transfer of Eksterior Routing information
( between peer-AS) and as identity from AS itself.
Have 2 AS Number type, that are:
1. Public AS number 2. Private AS number
More information about AS Number, can read atRFC1930.
4. WHEN AS NUMBER NEEDED?
Public AS number needed if a AS
Public needed when a AS will transfer of routing information with other AS which reside in Internet.
That is: all route coming from AS which visibel in Internet.
5. WHEN PRIVATE ASN CAN BE USED. ?
AS Number Private can be used when a AS will only
conduct BGP with one Provider.
Because policy routing between the AS & mentioned provider will not seen in Internet,
hence ASN Private can be used for this requirement.
IANA had Provide special range Private ASN can be used, that are:
AS64512 s/d AS65535
6. CONDITION PROFFERING of PUBLIC ASN.
a. Enclosing Prefix IP address to will be announce.
b. There are requirement Multihoming / will connecting at least
to 2 uplink.
c. ASN was requested which implementation in range of time
2 week after diapproved.
7. PROCESS PROFFERING of PUBLIC ASN
FOR THE MEMBER OF APJII.
a. Finishing APJII-ID administrative affair. For this matter
can contact billing@apjii.or.id
b. Fulfilling all " Condition Proffering of Public ASN"
c. Fill Form ASN, at link following:
http://www.idnic.net/services/asn-request.htm
d. Send form which have been filled to hostmaster@apjii.or.id
8. PROFFERING of PUBLIC ASN FOR THE
SMALL OF MULTIHOMING
a. Is raised to through ISP.
b. Fulfilling all "Condition Proffering of Public ASN"
c. If that customer set mind on shall no longger incircuit
to that ISP, hence ASN have to be returned. For this matter, agreement there must be written with pertinent ISP.
9. MANAGE PUBLIC ASN
a. When happened change of peer-ASN data, hence must be done
updating to the data.
b. Use password MNT-BY your ISP in updating this database.
c. Updating can be can be conducted by at link following.:
http://www.apnic.net/db/aut-num.html
10. RETURN of PUBLIC ASN
Hostmaster APJII will evaluate in specified period
to usage of the resources.
If the resources shall no longger be used for the requirement of
Multihoming including:
- For Private Peering
- Singlehoming
- Not be used at all.
Hence APJII hostmaster will do return to
the resources if things above fufilled.
