XRv 5.1.1 - Working/non working features and roadmap

[daniel.dib]

Hi,

Cisco recently released Cisco XRv 5.1.1 which is IOS XR running in a VM. I thought it would be nice track features working not working and if Cisco could comment on the roadmap.

Working:

ISIS

BGP

LDP

Not working:

EoMPLS

VPLS

Control plane is up for EoMPLS and VPLS but no traffic passes through. Post anything you have tested.

Hello, sharawy_2001,

What version are you using.  I'm using XRv 5.1.2 and I simply can't establish any IS-IS adjacency through sub-interfaces.

Through interfaces, it runs smoothly.  Did you make any special configuration to get it running?

Kind regards!

Hello

Yes this is a known issue. It is related to PDU MTUs

You can try to change clns mtu or disable hello padding

Thanks

Hello, Sherif,

Sorry for taking too long to answer.  I just would like to let you know that it was exactly what you said.  It was an issue.  Thanks this plus many other fixed small details, I could correctly study and pass my CCIE SP. :-)

Thank you!

[Sherif Atef Ahmed Ismail]

Big congratulations dear :)

SNMPv3 works

Here is my statement:

snmp-server user evanr observium v3 auth md5 Password05$ priv aes 128 Password05$
snmp-server view observium iso included
snmp-server group observium v3 auth read observium write observium

control-plane
 management-plane
  inband
   interface GigabitEthernet0/0/0/0
    allow SNMP peer
     address ipv4 172.16.1.4
     !
   !
  !
 !
!

Edit: Tried with sha and aes 128 and it worked with observium

Tried with sha and aes 256 and it would not work. Not sure if this is a limitation of xrv or of observium

Hello all,

during my tests I experienced that the ethernet OAM, CFM and L2VPN  (Bridge with BVI and PBB) doesn't work on ios-xrv.

Relating on OAM and CFM seem the ios-xrv have not the software module enabled.

Relating on l2vpn we see the packets  arrives on the l2-subint but they aren't sent to the bridge.

Any comments about this ?

Thanks

Isacco

Hi,

I was installed the XRv just a couple of days ago, and would like to report, that I couldn't find a way to activate the  "per-packet load-sharing" feature.

[dangleminh]

I've always got core dump whenever try to apply QoS policy on XRv interface. Anyone has the same issues?

[Sherif Atef Ahmed Ismail]

Dears

Have you tried mVPN with XRv. OIL interface at XRv is always null. Not sure from where is the issue

Please check below for details

Many Thanks

[yuribank415]

Yup. Same issue here with mVPN.

[Sherif Atef Ahmed Ismail]

Many thanks .. that was driving me crazy :)

[sukhjit.hayre]

class & policy-maps don't seem to work or commit, following on from previous poster who said he gets a core dump when applying the service-policy at the interface level....

I also received the same problem when I tried to commit service-policy. Here's a copy of what I did and what I got.
