FILE:	AS.HLP   

HELP:	An AS is not in the routing tables. If there are alert(s) about
        the EGP peer(s) for this AS use the EGP help screen. 
        If this alert is about "onenet" look in the file:
        ~pingky/Help/ONE.HLP
 

What it is:
            An Autonomous System is a (mostly) administrative grouping
            of networks. There are one or more ASs associated with each NSS.
            The backbone routes via ASs. When a packet enters the backbone
            The NSS looks up what AS the destination network is part of.
            This is in the netstat -Nn tables. The NSS then looks up what 
            pspf to direct the packet to in order to get to that AS.
            It uses the netstat -Rn tables for this step. 
            If a net is not found in the Nn tables it is looked up in
            the conventional rn tables which directly map a net to an
            interface. (this is how routing is done when the packet 
            reaches the e-psp)
            The NSS builds these tables based on information provided it
            by the EGP session between the EGP peer and the RCP. 
            If an AS drops out of the routing tables then there is likely 
            a problem with the EGP session between the RCP and the EGP peer. 
             
    
What to do:
                Confirm the alert is valid by issuing he following command
                from an RCP:
                netstat -Nn | grep ###     (### is the AS number)
                Numbers in the left column are networks and the right column
                contains the AS they are associated with. If the AS the         
                alert refers to does not show up it is a class one outage. 
                If other ASs reachable from the same e-psp are in the
                routing tables it is likely a problem with the site's EGP
                peer and they should be contacted. Try reaching appropiate
                contacts via phone first. If no one is available send email
                to as###@merit.edu (### is the appropiate AS number)
                If all the ASs associated with a particular NSS disappear 
                from the routing tables the problem might be with the NSS.
                Check /usr/adm/messages for "cease" messages. It might
                be necessary to turn on EGP tracing to closer examine what
                is really happening. (you should probably get assistance 
                from a shift manager at this point)

Escalation procedure:
	Contact a hotdog within 15 minutes if it is a class 1 outage.
        See the section on escalation in NOC-DOC for further info.  

Further Information:

How to Report:
        There is a mail group for each AS on merit.edu. 
        They use the format asxx 
        where xx is the AS number.

Pending Outage:

Current Condition: 
        EGP peers and the ASs they serve are constantly changing. . . 
        Use the topology database for the most up to date info.

Note:
	   This is just a sample form.  Put anything you like here 
	for the help screen.
