BGP strange problem on M10i

Hello all,

We are facing some issues on Juniper M10i, i.e.

First, we had to hard reset the bgp peer whenever we change the policies
(inbound policy) that we had set. By just doing soft reset the router will
not take effect of that changed policies until we do hard reset. Sometimes
even after hard reset, some strange issue were faced as for command:-

# sh bgp summary -

shows the peer is established but the line Active/Received/Accepted shows
0/0/0 respectively. However, we can view the received route on BGP table but
it does not announce any prefixes towards that peer for return traffic. Last
time when we had deactivated BGP, it wasn't updated-( BGP remained active).
Only after rebooting the RE, the router operates as configured.

If anyone has faced similar issue, I would appreciated any sort of help in
this regard.

Thank you,

Ramesh Karki

You shouldn't need to do any kind of reset; on JUNOS, policy changes are
applied on commit (although it can take a few seconds to work through a
full BGP table).

You didn't mention what version of JUNOS you are running (always an
important thing to include when discussing possible bugs).

we had identical symptoms on an MX960 a couple months back. "restart
routing" was required. This was the first & last time we saw this. I
think we were on 9.3R2.8 back then.

Kind regards,

Felix

Re: BGP strange problem on M10i [In reply to]

Hi,
The version we are using is JunOS 9.2R2.15

I also supposed that Junos do not require any kind of reset, but when I add
any new prefixes (ow
n by AS or its customers) on policy-statement to block incoming via upstream
and commit, it does not take effect. But when I hard reset the peer then
only it takes on effect.

Currently we peering with Tier One1 ISP with two location (Multi-homing to
the single AS), and got a full BGP table from both side.

Thank you Ramesh.

If you have NSR configured, then have a look at PR/396291

Re: BGP strange problem on M10i [In reply to]

Hi,

Thank for the response and for that Bug information.

To achieve high availability we have configured Graceful Routing Engine
Switchover with Non-Stop Routing (NSR). So, what do you like to suggest us
?, either change the configuration with Graceful Restart or upgrade the
JunOS.

Your help will be appreciated.

Thank you

Ramesh

Re: BGP strange problem on M10i [In reply to]

Hi Ramesh,

Well, that should be your call. But till the time you make it & for time
being with your current configuration, whenever you want to make any
change to your import policy you can first deactivate NSR & then commit.
NSR can be later reactivated.

Thanks & Regards,

Tarique A. Nalkhande
