After all needed interfaces ( for example: interface "a1", vrf "vrf1", and "a1" is binded to "vrf1" ) are ready/created, then restart/start frr. zebra at startup will call `netlink_interface()` to process all interfaces and notify all clients, but its calling `get_iflink_speed()` maybe fails for unexpected order of the coming interfaces: when processing "a1", "vrf1" maybe is unknown at that time. `if_zebra_speed_update()` timer is introduced to deal with this order problem. Currently only ospfd and ospf6d deal with this speed change to recalculated route cost. ospfd can deal with this change, but ospf6d will wrongly missed it. Since both `ipv6 ospf6 cost COST` and `auto-cost reference-bandwidth COST` are not set, cost of this ospf6 interface should be calculated with interface speed, but it is wrongly kept to `10`, which is based on interface speed being `0` for it missed speed change. Further, ECMP function becomes invalid after restart frr, beacuse some ospf6 interfaces of one ECMP are wrongly with cost `10`. To avoid missing, recalculate cost for ospf6 interfaces based on potentially changed speed. Signed-off-by: anlan_cs <vic.lan@pica8.com> |

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.
