Extreme X670-G2 - IP Fabric with BGP evpn and xvlan

Epafras_Schaden — Mon, 24 Sep 2018 23:56:00 GMT

Hello,

Can anyone share some documentation or an example of configuration to Extreme EXOS (X670-G2) about an IP Fabric configuration using BGP EVPN and VXLAN. I tried hard to find docs to this in EXOS but unsuccessful.

Thanks,

Epafras

The closest thing is on p. 322 of the EXOS 22.6 User Guide.

Hello Lisa, I just figure out the configuration, but now, I just posted about this a seconds ago. Do you have any suggestion ?

----------------------------------------------------------------------------------

Hello guys,

Recently I post a question about vxlan configuration on Extreme Switches. Well, I've walked a little bit since that, but now i have maybe a problem:

I figured out that, once you enable EVPN encapsulation on Juniper BGP sessions, AFI/SAFI 25/70 are used to establish the sessions.

In EXOS, AF 1 SAFI 241 are used. The problem is: This is a proprietary afi/safi [ " The BGP implementation for ExtremeXOS supports carrying VXLAN VNI and LTEP combinations as MBGP routes using a proprietary af/saf combination. " ] according to my research.

So, this is what we have:

Oct 8 12:08:52.288289 BGP RECV MP capability AFI=1, SAFI=241
Oct 8 12:08:52.288290 BGP RECV Refresh capability, code=2
Oct 8 12:08:52.288291 BGP RECV Refresh capability, code=128
Oct 8 12:08:52.288292 BGP RECV Unrecognized capability 70
Oct 8 12:08:52.288306 BGP RECV Param data (18 bytes): 01 04 00 01 00 f1 02 00 80 00 46 00 41 04 00 00
Oct 8 12:08:52.288344 bgp_parse_open_options: peer 3.3.3.3 (Internal AS 65000): unsupported AF 1 SAFI 241

It appears that EXOS will not talk to Juniper switches in a EVPN with VXLAN environment.

Some body had this problem and figure out any solution ? 😞

Thanks for any help.

Hello Alexander. Unfortunately not. Extreme Switches was replaced by Juniper’s.

Thx. Epafras

Hello!

it was before 30.x train/

from v.30.3 User guide (p.1589):

Identify the network address family with AFI/SAFI—For VXLAN, AFI of 25 (L2VPN) and a SAFI
(EVPN) of 70 is used.

So now EN cross-compatible with any who follow RFC.

Check RN and UG and use right OS for your deployment.
