#21 Adj strange behaviour
Creates a large number of down adjacency in show isis
nei with one of the neighbors.
vty gets very slow due to that.
thanks in advance !
Maybe I'll try to look but i do not really know how to
debug.
I'm not a C expert.
Maybe we'll try to hire a student in order to help
debugging.

Odd behavoiur indeed. My first quess is that this is caused
by too small a value for "isis hello-interval" Unlike in IOS
this value is specified in milliseconds in ISISd.

Same behavior for me: I have two linux boxes running isisid
0.93pre2, and they keep on forming new "down" adjacencies.
They also form several "up" adjacencies, though. I have tried
to increase the hello timer, but:
omnibook-isisd# conf t
omnibook-isisd(config)# int eth0
omnibook-isisd(config-if)# isis hello-interval 100000
omnibook-isisd(config-if)# end
omnibook-isisd# wr t
[...]
interface eth0
ip router isis TEST
ip address 10.31.22.200/20
ipv6 address fe80::210:a4ff:fefb:22ec/10
isis circuit-type level-1
isis hello-interval 34464
And if I set hello-interval to say 200000 (max is declared by
the CLI to be 4294967), config then says "isis hello-interval
3392" (???)
At any rate, it seems to always create the strange 'down'
and 'up' adjacencies regardless of the hello timer.
Thanks,

The version in cvs now has "isis hello interval" in *seconds*.
I do not know if the msec interval was the cause of this
behaviour, but couldn't think of any other reason either.
The problem might also be in the implementation of adjacency
database, but it's hard to find the error, since i'm not
able to reproduce this bug.
The expired adjacencies should be removed by the
adj_expire() thread..
do you get "holding time expired" on your log file
