Re: J2320 - V12.4 BGP And Firewall Setup

Hi,

 

Ok so BGP has come up and i`m seeing active routes in the table but i cannot get any traffic to pass through the router itself e.g. ping or see any devices at either end. I have at the moment set all zones to all with all services to allow apart from the default global which is set to deny.

The two things to check then are to confirm that sessions are being accepted and created for your traffic.  Setup the ping and then use:

 

show security flow session source-prefix 1.1.1.1 destination-prefix 2.2.2.2

 

This should show the accepted sessions with nat and packet counts.  If there are no sessions you will need to enable trace options to find out why.

 

Second thing to confirm is that the remote side has the return route for the traffic and that they ahve polcies to accept the traffic as well.

Support for 1Gbps SFP in MIC3-3D-10XGE-SFPP?

Does anyone know if the MIC3-3D-10XGE-SFPP card supports 1Gbps SFP's?

I know there is the MIC-3D-20GE-SFP for that but since we are migrating from 1Gbps to 10Gbps I'd like the MIC to supprt both speeds.

MIC3-3D-10XGE-SFPP is 10G / SFP+ only.

Hi,

 

Stil not having much luck.... I have setup a pair of J2320`s running V12 firmware, configured BGP between them (to simulate the MPLS proviers end) and i can see those routes replicating between the routers. On the head office end i can see and connect to all devices on the remote end but not the other way round e.g. communicating with head office end from the remote network. When running a trace i get as far as the external interface on the head office end`s router but no further. Machines in the head office end have a static route pointing back at the branch router.

 

Sorry it`s quite vague, let me know if you need any other info.

 

Cheers,

Hi,

 

This MIC has 10 Gig posrts only and 1G SFPs can not be used.

You can follow below links for more detail about this mic.

Securiity policies that permit the traffic are needed in the direction of the initiator (from-zone) of the traffic to the destination (to-zone)

 

set security policy from-zone NAME to-zone NAME

 

Both SRX need to have a policy that permits the traffic.

 

So in your case one of the two SRX does not have a policy from the hub zone to the spoke zone for the traffic to be permitted.  You confirm the existence of the sessions with the show security flow command.

 

If the session is not being created you can use trace options to get the details on why.

Some enlightenment would be appreciated.

Need Help : OSPFv3 issue on Juniper MP-BGP --> OSPF

$
0
0

I am currently using OSPFv3 between the CE and PE in the following scenario. The PEs are Juniper and CEs, another vendor (Cisco). I have enabled the address families/realms for both IPv4 and IPv6  between the CEs and the PEs. OSPF is established and I can see the OSPFv3 routes from the local CE on the local PE which is advertised through MP-BGP to the remote PE. In other words, I can see all OSPFv3 routes in the VPNv4 table. However, remote routes that is imported into the local PE (VRF) is not advertised into OSPFv3. I have configured export/Import policy for OSPF to export the BGP routes from the VRF to OSPF and also for loop prevention using tagging but seems that's not working as I can't see any remote routes in the local CPEs. I checked the OSPFv3 database (and also in realm IPv4-Unicast), no remote route is installed. With OSPFv2, everything works perfect with the exact same configurations w.r.t MPLS VPN.

 

Any idea what's going on please? Any help will be appreciated.

 

Thanks.

100Mb SFP on ACX5048

Hi,

 

I know that this can support 1Gb SFPs, but has anyone managed to test whether you can use a copper SFP and connect a device at 100Mb?

Will the ACS5048 support 100Mb F/D speeds using a 1Gb copper SFP?

 

Thanks in advance,

Matt

Hi, mskipsey!

 

I don't personally have the ACX 5048 but reviewing the ACX 5000 series documentation it does not appear so. Here are the relevant portions of the document.

 

 

All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

Source - Port Panel of an ACX5048 Router

 

 

And on the Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for an ACX5000 Router page you can see for the Gigabit transceivers only the 1000Mbps rate is supported.

 

I hope this helps.

I can confirm that 100 Mbps optics are not supported on ACX5048 - with Junos 17.3R1 the smaller platform now supports for 100 Mbps but a bit strange that it wasn't a focus for ACX5000.

 

Hardware

  • Support for 100 MB Optics (ACX500, ACX1000, ACX1100, ACX2100, ACX2200, ACX4000)—Starting in Junos OS Release 17.3R1, ACX Series Universal Access Routers (ACX500, ACX1000, ACX1100, ACX2100, ACX2200, ACX4000) support 100 MB Ethernet optics.

    [See Hardware Compatibility Tool]

Interesting find, as that does appear to confirm that the other ACX platforms now do support 100Mb optics, but not the 5000 series.

 

https://www.juniper.net/documentation/en_US/junos/information-products/topic-collections/release-notes/17.3/topic-120780.html#rn-junos-acx-new-and-changed-features

Support for 100 MB Optics (ACX500, ACX1000, ACX1100, ACX2100, ACX2200, ACX4000)—Starting in Junos OS Release 17.3R1, ACX Series Universal Access Routers (ACX500, ACX1000, ACX1100, ACX2100, ACX2200, ACX4000) support 100 MB Ethernet optics.

 

Bummer.

 

Some of our services are handed off to us on 100Mb copper.

 

I guess we'll have to put an intermediary EX switch between the ACX5048 and the network provider's NTE.
