ASR 9000 VXLAN support

Hello Cisco community,

 

I am trying to lab VXLAN on 3 routers - 2x ASR9910 and 1x ASR9006 with IOS-XR 5.3.3

 

All of them should support VXLAN encasulation and BUM replication over multicast. Unfortunately it works only on newer ASR9910. Those 2 routers does not see ASR9006 in nve peers and it looks like ASR9006 is not able to encapsulate and send traffic over VXLAN.

Is it possible that I am missing the licensing? I found out that there is a RTU: Part #: S-A9K-VXLN-RTU-10 ASR 9000 VxLAN 10Gbps Right to Use License 

 

But it works on ASR9910 without any license..

 

Thank You.

Re: ASR 9000 VXLAN support

Can you be more specific when you say VXLAN EVPN is not working?

VXLAN Support
Hardware:
- Support on typhoon (-TR and -SE) for all features introduced in 5.2.0 to 6.2.1with few exceptions:

** Not supported on Typhoon:

* EVPN-VXLAN to VPLS L2 Gateway
* EVPN ESI Multi pathing for VXLAN - RFC compliance
* L2VPN ISSU for ASR9K
- No support on typhoon for features to be introduced in 6.3.1 and later.
- Supported on Tomahawk all line cards (-TR and -SE) (XR 5.3.1 or higher)



1/ Could you please confirm that VXLAN BGP EVPN (L2GW) is supported on typhoon
line cards?
Yes

2/ Could you please detail which VXLAN feature wont be supported on typhoon
cards?
ESI Multipath per-flow load balancing is not supported on Typhoon LC,
Typhoon LC only can do per-EVI ESI Multipath load balancing.

Re: ASR 9000 VXLAN support

On the 9006 can you make sure that you are using LC3 for VxLAN?

The other LCs are the older trident cards (-B) and don't support VxLAN due to limited uCode space.

 

In fact even the typhoon based LCs have limited VxLAN support, only the 4x100, 8x100, MOD200, and MOD400 (tomahawk LCs) have full VxLAN support.

Re: ASR 9000 VXLAN support

Thank You, I will try to test it on the typhoon card.

What do you mean by limited support? We only need L2VPNs to run over vxlan using multicast (PIM-SM) for BUM replication.

Looks like VXLAN EVPN or ingress replication is not supported even on newer ASR9910 running 6.x code

Typhoon LC only can do per-EVI ESI Multipath load balancing.

Re: ASR 9000 VXLAN support

Sorry Sam, you are right VXLAN EVPN is supported.

 

RP/0/RSP0/CPU0:R1(config-if)#member vni 10008 host-reachabilty protocol bgp 

 

so only ingress replication is not supported.

 

Thank You.

Re: ASR 9000 VXLAN support

If you are planning to run VXLAN, I would say go to a 6.x+ version instead.

Re: ASR 9000 VXLAN support

Of course a 6.x version is recommended, but the hardware on the router with the problem doesn't support 6.x. If they wish to continue using the old hardware and support VxLAN on typhoon then the code they are on is fine, they just won't get every feature of VxLAN, it all depends on what they need.
