[c-nsp] Order of booting line cards in C6500 and routing process delay

[Geert Nijs]

Hello,

We are running subsecond OSPF in our enterprise LAN and just upgraded our
core switches. When one core was being brought up, we lost 30 seconds of
pings to our server farm (which is hanging of the core switches redundantly
in L3). The setup is a bit more complicated, but analysing the boot, i
noticed that all OSPF links came up rather "randomly" and i think the
downtime came from blackholing traffic because neighborships were still
missing. For example: the server farm OSPF neighborship gets up first. Since
this is a stubby area, the only route added is a default route. The server
farm starts to loadbalance to the two cores, but on one of the core switches
the downstream links are not yet up, resulting in blackholing traffic.
So my question is: can i put a WAIT timer on the routing process so that it
waits until all linecards are booted and then initiates the routing process
(preferably in a certain predetermined sequence) ?
Or on the server farm core, can i put a HOLD timer on the ospf neighborship
with the core ?
( a bit like you can configure a PRE-EMPT delay on HSRP neighbors ?)

regards,
Geert
