Hi Waris,
So is the 15.2(4)S3 a best stable one please?
Also would it have the knob to only enable 3x10GigE with the license for 2
additional 10GigE interfaces -or that one is only supported in 15.3 please?
Thank you very much
adam

Team,
The issue is resolved and the fix will be available in the following
releases
-15.3(2)S/XE3.9.0S has this fix integrated and available to customers.
-Fix integrated in both 15.2(4)S3/XE3.7.3S and 15.3(1)S2/XE3.8.2S and will
release them to CCO on 4/23 and 4/30 respectively.

Hi,
Thank you Waris for confirming my suspicions. We can't flap the interface as
we have 50+ customers on it (all others are p2p vc). We've tried removing
the vfi and re-adding it, but no avail.
Is there any workaround available?
kind regards
Pshem

Hi Pashem,
You are right there is an issue with the control word between the two
platforms and this issue is in the process of getting fixed. I'll get back
to you with the date of fixed image. BTW can you try to flap the interface?

Hi,
The discovery works fine - we have the prefix length specified on the
Me3600x, both devices know that they have to build the LSP it's just
not coming up and I think it's not coming up because the control word
can not be negotiated properly.
kind regards

Hi Pshem,
Isn't the "prefix-length-size 2" the problem?
>From Cisco web page:
Interoperability Between Cisco IOS XR and Cisco IOS on VPLS LDP Signaling
The Cisco IOS Software encodes the NLRI length in the fist byte in bits
format in the BGP Update message. However, the Cisco IOS XR Software
interprets the NLRI length in 2 bytes. Therefore, when the BGP neighbor with
VPLS-VPWS address family is configured between the IOS and the IOS XR, NLRI
mismatch can happen, leading to flapping between neighbors. To avoid this
conflict, IOS supports prefix-length-size 2 command that needs to be enabled
for IOS to work with IOS XR. When the prefix-length-size 2 command is
configured in IOS, the NLRI length is encoded in bytes. This configuration
is mandatory for IOS to work with IOS XR.
This is a sample IOS configuration with the prefix-length-size 2 command:
router bgp 1
address-family l2vpn vpls
neighbor 5.5.5.2 activate
neighbor 5.5.5.2 prefix-length-size 2 --------> NLRI length = 2 bytes
exit-address-family

Hi,
I hope that collective knowledge can help me here.
We're trying to build a simple VPLS between an ASR9k (IOS XR 4.2.3) and
ME3600x (IOS 15.3(1)S) using BGP autodiscovery and LDP for signaling.
THe VPLS is not coming up,as the pseudowires are not up, I've located the
issue to the control word - the 9k runs with 'disabled' whilst the ME3600x
runs on autosense and that is failing as it results on 'control word on':
