I've noticed since updating to current from 4.0-current in January to
-current "now" that certain commands through bgpctl seem to just
hang .. (we've tried this with various snapshots every 2 weeks or so
since January) as well as trying a full build.
If I do a bgpctl reload (100+ peers per production router) and then
within a minute or so do a "bgpctl show" then bgpctl's output just
hangs (I've left it for nearly an hour and nothing has appeared
beyond the headers)
Also regardless of a reload, attempting to show rib nei a.b.c.d out
also just seems to hang
bgpctl show rib nei 80.252.124.1 out
flags: * = Valid, > = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete
flags destination gateway lpref med aspath origin
and no more output
Whilst the same command on our 4.0-current boxes generates the sort
of output I would expect
[EMAIL PROTECTED] time bgpctl show rib nei 80.252.124.3 out | wc -l
64171
real 0m6.374s
user 0m1.461s
sys 0m0.086s
What (if anything more) can I do to help diagnose this further?
I have a test setup on a box internally with the following config and
-current as of this morning
AS 65123
fib-update yes
route-collector no
network 80.252.127.0/24
group fidonet {
softreconfig in yes
softreconfig out yes
multihop 3
announce self
set nexthop self
remote-as 8282
neighbor 80.252.124.1
neighbor 80.252.124.3
}
Which hangs
bash-3.2# time bgpctl show rib nei 80.252.124.1 out
flags: * = Valid, > = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete
flags destination gateway lpref med aspath origin
^C
real 1m50.758s
user 0m0.000s
sys 0m0.000s
If I turn off softreconfig then I get mixed results
bash-3.2# time bgpctl show rib nei 80.252.124.1 out
flags: * = Valid, > = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete
flags destination gateway lpref med aspath origin
AI*> 80.252.127.0/24 0.0.0.0 100 0 i

bash-3.2# time bgpctl show rib nei 80.252.124.1 out

flags destination gateway lpref med aspath origin
^C

(our border routers are 3Ghz P4-HT .. our test box is an old G4 mac
mini .. so I would expect a slower performance on the mac mini .. all
boxes have at least 1Gb ram)
I have also noticed that if I do a bgpctl show rib nei x out in one
window, and then do a bgpctl reload in another window the output
appears almost instantly after the reload
bash-3.2# time bgpctl show rib nei 80.252.124.3 out
flags: * = Valid, > = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete

(JPM - perform reload in another window)
