I have a Juniper M20 with Junos 9.4R4.5, which all of the sudden
doesn't support SSH login:

Hi Clarke,
Lot's of good insight here. You've put together some pretty good stuff.
Have you thought about putting it on a blog somewhere?

We use the Unix tool samplicator at our Netflow collector to
symplicate the Netflow packet to multiple UDP ports. Multiple
collectors listening to different ports. This might work for you as
well.

Guys
Does anyone of you could suggest me where I can find memory
modules for SSB-E ?
Thanks

I have one M20 SSB-E(710-001951) which uses SMS SM57208809WDTX6 64MB
SDRAM DIMM. It uses Samsung K4E6408120-TL50 memory chips. Maybe this
information helps if you should accidentally find a SM57208809WDTX6
from second-hand market.

Dear All
I have a setup where I need to load balancing routes received from 2 RR in
IPV4 environment (not VPN-IPV4)
I have my PE (let's called PE1) connected to 2 RR (cluster), my destination

Not sure if others will have a better answer, but I don't think this is
possible. As far as I know BGP doesn't support multi-pathing so there isn't
a way to have two next hops used for the same prefix. You might be able to
peer with a loopback address and use your IGP to create equal cost routes
You will need the 128MB DRAM upgrade if you have lots of routes as well
as a couple of thousand of arp entrys. This will fill the memory on the
SSB-E very fast and once you hit the 64MB limit the router will do weird
things (e.g. several ip address no longer reachable, routes not being
installed
Keegan,
Look into add-path, something that is not supported in JUNOS yet, but will
be sometime this year.

Have you tried the advertise-inactive knob on the RR? I can't guarantee that
this will work but it just might also advertise the route towards PE3 as well.
Of course, if this works, then you would need to enable multipathing on PE1
accordingly.

just to clarify ,

PE2 with 2 link , 1 to RR1 (let's call it link 1) and 1 to RR2 (link 2)
PE3 with 2 link , 1 to RR1 (let's call it Link 3) and 1 to RR2 (link4)
you could set local pref to link to PE2 to 150 (RR1 to PE2 will be
preferred), and link 2 (PE2 to RR2) as standard 100
I thought advertise inactive just configured the routers to advertise the
entire BGP RIB instead of only advertising the routes in the routing-table.
How would you configure multipathing once the routes were there?

Hi Keegan,

Nope. BGP advertises by default single best path. Any subsequent
advertisement will be an implicit withdraw.
Hi Humair,

I think the advertise inactive knob turns that off, but I don't know for

routers. The reason for it is the size of the BGP table. So if the table
is 400k routes and you have 5 different ISP's and you advertise every route

By default Junos and IOS-XR advertise only those best path in BGP
which actually are installed into forwarding. Advertising inactive
knob will overwrite it.
Wouldn't this lead to traffic being blackholed? If all the routes for a
given destination are inactive would this
I'd consider preceding certain route ranges across the links. Prefer a range of
routes on each link. Depending how you write your filters, you'll be able to
tune things a bit as well as keep redundancy. The return path can be more
difficult, but I find that as prepends or more specific route
I always thought that advertise-inactive was to make a juniper act like a cisco
with regard to BGP route announcements, when, by default, differences in route
preference cause a JUNI to prefer an IGP route while ios prefer the bgp routs
over IGP.
In junos, only the active route is

Hello,
i see that there now is a new enhanced SCB for MX series which is

Hi,
I've got an SRX240 runing 10.4R4.5 running at a brach site serving as
the site gateway and I figure out a way to write DSCP values before traffic
is encrypted into an IPSec VPN due to the SRX being the only device at the
site. The only place I can apply outbound DSCP marking is on the
What I got from juniper is that the enhanced SCB will only be supported in
11.4 which is April 2012.
Even if you use the enhanced SCB today in your mx chassis you are only going to
get 40G per SCB(same as the existing SCB),but with 11.4 you get 80G.
