Donald Sharp 8bb0831e23 Per AFI redist registrations
The problem is that zclient->redist[ZEBRA_ROUTE_MAX] used for storing a
client’s redist state, has no address-family qualification. This means
a client can only store its interest in a protocol (connected, static etc.),
but cant choose IPv4 or ipv6 with that. This hindered implementation on
client sides to manage redistribution of ipv4 and ipv6 both.

BGP's redistribution of protocols like connected/static is one such place.

One fix could be to overload this and flap the redist connection each time
any new afi is added for redist, but that may have side-effects on the
existing afi redist.

The cleaner way is to modify redist data-structure to also take AFI, and adjust
routines that deal with it, so that a client can register for a protocol
redistribution based on the AFI. BGP already maintains redistribution state
based on afi and protocol (bgp->redist[AFI_MAX][ZEBRA_ROUTE_MAX]). This patch
takes care of filling up the gap in zclient/zserv redistribution state to
also use AFI qualification.

		  Zebra OSPF daemon for IPv6 network

README for newer code is not yet. General usage should remain
the same. For further usage, see command helps by typing '?'
in vty, and then imagin ! ;p) Previous README contents follows.

		  Zebra OSPF daemon for IPv6 network

			     2001/12/20

Zebra OSPF6d is OSPF version 3 daemon which is specified by
"OSPF for IPv6" (RFC 2740).

*** NOTE ***
  Zebra ospf6d is in development yet. It may lack some functionalities,
  and may have some bugs. Use the latest version from the anoncvs
  repository (http://www.zebra.org/cvs.html) !

This file README is like memo yet, so please feel free to ask
<yasu@sfc.wide.ad.jp> by E-mail. Patches will be appriciated.

ospf6d's vty port was default to 2606/tcp.
Use commands below.

VIEW NODE:
  show ipv6 ospf6
    To see Router-ID, uptime of ospf6d, some statistics.

  show ipv6 ospf6 database ...
    This command shows LSA database. You can specify
    LS-type/LS-ID/Advertising-Router of LSAs. '*' is recognized.

  show ipv6 ospf6 interface ...
    To see the status of the OSPF interface, and the configuration
    like interface costs.

  show ipv6 ospf6 neighbor ...
    Shows state of neighbors and choosed (Backup) DR on the I/F.

  show ipv6 ospf6 route (X::X)
    This command shows internal routing table of the ospf6d.
    Routes not calculated by OSPFv3 (like connected routes)
    are not shown. If Address is specified (X::X), shows the route
    that the address matches.

  show ipv6 ospf6 route redistribute (X::X)
    Shows the routes advertised as AS-External routes by the router
    itself. If Address is specified (X::X), shows the route
    that the address matches.

CONFIG NODE:
  interface NAME
    To enter INTERFACE NODE

  router ospf6 ...
    To enter OSPF6 NODE

INTERFACE NODE:
  ipv6 ospf6 cost COST
    Sets the interface's output cost. Depends on interface bandwidth by default.

  ipv6 ospf6 hello-interval HELLOINTERVAL
    Sets the interface's Hello Interval. default 10

  ipv6 ospf6 dead-interval DEADINTERVAL
    Sets the interface's Router Dead Interval. default 40

  ipv6 ospf6 retransmit-interval RETRANSMITINTERVAL
    Sets the interface's Rxmt Interval. default 5

  ipv6 ospf6 priority PRIORITY
    Sets the interface's Router Priority. default 1

  ipv6 ospf6 transmit-delay TRANSMITDELAY
    Sets the interface's Inf-Trans-Delay. default 1

OSPF6 NODE:
  router-id A.B.C.D
    Sets the router's Router-ID

  interface NAME area AREA
    Binds interface to specified Area, and start
    sending OSPFv3 packets.

  auto-cost reference-bandwidth COST
    Sets the reference bandwidth for cost calculations, where this
    bandwidth is considered equivalent to an OSPF cost of 1, specified
    in Mbits/s. The default is 100Mbit/s (i.e. a link of bandwidth
    100Mbit/s or higher will have a cost of 1. Cost of lower bandwidth
    links will be scaled with reference to this cost).  This
    configuration setting MUST be consistent across all routers within
    the OSPF domain.

Sample configuration is in ospf6d.conf.sample.
