Hi list
Are you using Juniper's vRR (virtual route reflector) as route reflector in
production?
Or do you have any experience of testing it?
Yes to both. I am running a pair of these on VMWare hosts (using the
15.1 "unified package" image).
There are a couple of things I have come across. First the VM's have a
constantly crashing and core dumping process, l2cpd.
As an example of what happens:
Jul 27 15:33:56 vrr1 l2cpd[34141]: stp_enable_modules : Failed to get
stp base mac address. All modules will remain
disabled.
Jul 27 15:33:57 vrr1 dfwd[3016]:
dfwdlib_process_client_disconnect:10762 num_client_id = 1
Jul 27 15:33:57 vrr1 dfwd[3016]:
dfwdlib_process_client_disconnect:10771 num_id_list[0] = 5

signal number 6. Core dumped!

That happens every minute.
The second issue is you cannot configure the em0 interface. I only need
a single interface on these VM's but I have had to add two interfaces.
The first interface I have just left disconnected so that the real
interface gets bumped to em1 which can be configured.
If you try to configure em0 this happens:
[edit]
me@vrr1# show interfaces em0
[edit]
me@vrr1# set interfaces em0 description test
[edit]
me@vrr1# commit
[edit interfaces]
'em0'
Interface em0 is not user configurable
error: configuration check-out failed
[edit]
me@vrr1#
I have not tried any of the earlier images and I have not tried to run
this with other virtualisation so YMMV.
Apart from the above issues everything else is working perfect for my
situation.
